Which among the following are commonly used for making safety pins?A. Wood and glassB. Plastic and glassC. Leather and plasticD. Steel and plastic Join Vedantu’s FREE Mastercalss Answer Verified Hint : The combination of more than one metal or mixture of metal and a nonmetal in a fixed proportion are known as alloys.
- Certain elements are added to the mixture in a specific ratio which alter the properties of metals and strengthen the metals.
- Complete Step By Step Answer: One of the widely used alloys in day-to-day life is steel.
- The base metal of steel is iron to which carbon is added in a specific ratio to improve its strength and fracture resistance.
The amount of carbon in steel varies up to $2.14\% $ of its weight.The pure iron is ductile, soft and gets corroded when exposed to moist air but on adding carbon to it enhances the property of iron and the alloy i.e., steel formed is hard, brittle and prevents corrosions.
- Hence, steel has many applications in domestic as well as industrial sectors.Some of the applications of steel are discussed below:-Used in making tools like knives, razors, blades etc.-Used in making the vessels.-Used in railway tracks, wheels and gears.
- Steel can also combine with polymers like plastic to give useful products.
One of the common examples is safety pins. Steel and plastic are commonly used in making safety pins. Hence, option (D) is the correct answer. Note : It is important to note that when steel is mixed with $10.5\% $ chromium, about $1.2\% $ carbon and other components like nickel and nitrogen.

What is the best material for safety pins?
Raw Materials – The most common metals used in safety pins are spring steel, brass, and stainless steel. Most fasteners without critical strength requirements are made from spring steel, an alloy of iron that has a high carbon content (more than 0.5%).
By varying the proportion of carbon added to iron, spring steel can have high tensile strength and resiliency that allows it to flex and return to its original shape. Brass is an alloy of approximately two-thirds copper and one-third zinc. More expensive than spring steel, this metal will polish up to a high luster.
It is nonmagnetic and easily worked into shape. The strength of brass is adequate for most safety pin applications. More expensive than brass, stainless steel is an alloy that includes chromium and nickel (manganese is sometimes used instead of nickel).
With a mirror-like finish, stainless steel is used when corrosion, temperature, and strength are considerations. However, for some safety pin applications, a type of low-carbon stainless steel—ferritic, which costs less than stainless steel—is used. Other raw materials include a variety of coatings and platings.
The most common finish on spring-steel pins is chrome, followed by a final wax coat. If the pin is to be subjected to damp environments or to a piece of cloth for a long period of time, other treatments are used to prevent stains from corrosion of the steel. One of these methods is to coat the pin with the chemical chromate, particularly on spring-steel safety pins.
Why are safety pins made of steel?
Steel is hard and tough in nature. It has high tensile strength. It is light in weight but high in strength. Safety pins are made up of steel to get sharp points.
What steel is used for pins?
Carbon steel and alloy steel are the most cost effective and versatile materials available for use in Coiled Pins. These materials are readily available, easy to process, and have very uniform and predictable performance characteristics.
Why are safety pins called that?
The Invention of the Safety Pin – The safety pin was invented while Hunt was twisting a piece of wire and trying to think of something that would help him pay off a debt of fifteen dollars. He later sold his patent rights to the safety pin for four hundred dollars to the man that he owed the money to.
What is a pin safety?
A PIN: is a tool to improve health and safety in a workplace, encouraging employers and workers to openly discuss health and safety hazards and risks in their workplace.
Is safety pin a magnetic material?
Erasers, plastic rulers are non-metals and non-metals do not possess magnetic property. But safety pins are metallic and are magnetic in nature.
Is a safety pin a magnet?
Answer. Safety pins, which are made of steel, being attracted to a bar magnet. The magnetic field of the magnet induces a small magnetic field in the steel pins, and the opposite magnetic poles than attract each other. The pins will remain magnetised for a time after the bar magnet has been removed.
What material is used for spring pins?
Coiled spring pins – Coiled spring pin. A coiled spring pin, also known as a spiral pin, is a self retaining engineered fastener manufactured by roll forming metal strip into a spiral cross section of 2 + 1 ⁄ 4 coils. Coiled spring pins have a body diameter larger than the recommended hole diameter and chamfers on both ends to facilitate starting the pin into the hole.
The spring action of the pin allows it to compress as it assumes the diameter of the hole. When coiled spring pins are installed, the compression starts at the outer edge and moves through the coils toward the center. Coiled pins continue to flex after insertion when a load is applied to the pin thus providing excellent performance to counter fatigue in dynamic applications.
Coiled spring pins were invented by Herman Koehl circa 1948. Coiled pins are commercially available in three different duties, standard (ISO 8750), heavy (ISO 8748) and light duty (ISO 8751), which provide for a variety of combinations of strength, flexibility and diameter to suit different mating host materials and performance requirements.
- Typical materials for coiled spring pins include high carbon steel, stainless steel and alloy 6150.
- Coiled pins are used extensively in cosmetic cases, automotive door handles and locks, and latches as hinge pins.
- They are also used as pivots and axles, for alignment and stopping, to fasten multiple components together—such as a gear and shaft—and even as ejector pins to remove motherboards from PCs.
The automotive and electrical industries use coiled pins in such products as steering boxes and columns, pumps, electric motors and circuit breakers.
What metal are the pins made from why?
Resins to make custom pins – Resins are another type of material used to make custom pins. Resins are synthetic materials made from a mixture of chemical components. Pins made of resin can be personalized with intricate and detailed designs, and can be made in many different shapes and sizes.
Resins have several advantages over other materials used to make custom pins. Firstly, the resins can be personalized with intricate designs, allowing highly detailed pins to be created. Second, resins are strong and durable, making them ideal for pins that will be used in harsh environments or worn on a daily basis.
Third, resins are cheap and easy to produce, making them ideal for large-scale production.
What are gold safety pins made of?

What metal are electrical pins made from?
Materials – Electrical connectors essentially consist of two classes of materials: conductors and insulators. Properties important to conductor materials are contact resistance, conductivity, mechanical strength, formability, and resilience, Insulators must have a high electrical resistance, withstand high temperatures, and be easy to manufacture for a precise fit.
- Electrodes in connectors are usually made of copper alloys, due to their good conductivity and malleability,
- 15 Alternatives include brass, phosphor bronze, and beryllium copper,
- The base electrode metal is often coated with another inert metal such as gold, nickel, or tin,
- The use of a coating material with good conductivity, mechanical robustness and corrosion resistance helps to reduce the influence of passivating oxide layers and surface adsorbates, which limit metal-to-metal contact patches and contribute to contact resistance.
For example, copper alloys have favorable mechanical properties for electrodes, but are hard to solder and prone to corrosion. Thus, copper pins are usually coated with gold to alleviate these pitfalls, especially for analog signals and high-reliability applications.
What steel is used for pins?
Carbon steel and alloy steel are the most cost effective and versatile materials available for use in Coiled Pins. These materials are readily available, easy to process, and have very uniform and predictable performance characteristics.
