What metals are made of metal keychains?

Metal Keychains have many shapes, such as cartoon shapes, brand shapes, simulation models, and even CPUs. The materials are generally copper, aluminum, etc., and the zinc alloy surface is mainly nickel-plated or rhodium-plated with anti-rust elements. So what metal materials are our metal keychains made of?

Here is the content list:

l Keychain made of zinc alloy

l Keychain made of brass

l Keychain made of stainless steel.

Keychain made of zinc alloy

Zinc alloys are alloys based on zinc added with other elements. The metal keychain made of zinc alloy has a low melting point, good fluidity, easy welding, brazing, and plastic processing. The metal keychain is corrosion-resistant in the atmosphere, and the residual material is convenient for recycling and remelting, but the metal keychain has low creep strength, Prone to dimensional changes caused by natural aging. Metal keychains are generally prepared by the melting method, die-casting or pressure-processed into materials.

Keychain made of brass

Brass is an alloy of copper and zinc, and various alloys composed of two or more elements are called special brass. Brass made of copper and zinc is called ordinary brass. Brass has strong wear resistance. Brass is often used to make valves, water pipes, and radiators. So made of brass, the metal keychain is particularly durable. The addition of tin to the brass used to make the keychain can significantly improve the heat resistance of the keychain, especially the ability to resist seawater corrosion. The addition of nickel to brass can significantly improve the corrosion resistance of brass keychains in the atmosphere and seawater. Nickel can also increase the recrystallization temperature of brass metal keychains and promote the formation of finer grains of metal keychains.

Keychain made of stainless steel

Stainless steel is the abbreviation of stainless and acid-resistant steel. Stainless steel is also the most important material for making metal keychains. And acid-resistant steel that is resistant to chemical corrosion media (acid, alkali, salt, etc.) corrosion can also be used to make metal keychains. Due to the difference in the chemical composition of the keychains made by the two, their corrosion resistance is different. Stainless steel is the abbreviation of stainless and acid-resistant steel. Ordinary stainless steel keychains are generally not resistant to chemical media corrosion, while acid-resistant steel keychains are generally non-corrosive. The term "stainless steel" refers to a single type of stainless steel, is also refers to more than one hundred industrial stainless steel. Each stainless steel developed has good performance in its specific keychain. The key to success is first to understand the purpose of the keychain, and then determine the correct steel grade for the keychain.
