Logo Zinc Alloy Souvenir 3D

Metal keychains come in a variety of shapes, including cartoon characters, company logos, simulation models, and even CPUs. Copper, aluminum, and other metals are commonly used, and the zinc alloy surface is nickel-plated or rhodium-plated with anti-rust components. So, what metal materials are used to make our metal keychains?


The keychain is composed of zinc alloy

Zinc alloys are alloys composed of zinc and additional elements. The zinc alloy keychain has a low melting point, and good fluidity, and is simple to weld, braze, and plastic process. The metal keychain is resistant to corrosion in the atmosphere, and the residual material is easy to recycle and remelt, but it has poor creep strength and is sensitive to dimensional changes produced by natural aging. Metal keychains are often made via melting, die-casting, or pressure processing. Related product: Logo Zinc Alloy Souvenir 3D keychain.


The keychain is constructed of brass

Brass is a copper and zinc alloy, and special brass refers to specific alloys made of two or more elements. Ordinary brass is composed of copper and zinc. Brass is extremely resistant to wear. Brass is frequently utilized in the manufacture of valves, water pipes, and radiators. The metal keychain is made of brass and is extremely robust.


The addition of tin to the brass used to produce the keychain can considerably improve its heat resistance, particularly its resistance to seawater corrosion. The addition of nickel to brass can considerably increase brass keychain corrosion resistance in the environment and seawater. Nickel can also raise the recrystallization temperature of brass metal keychains, causing finer grains to develop.


A stainless steel keychain

The shorthand for stainless and acid-resistant steel is stainless steel. Stainless steel is also the most commonly used material in the production of metal keychains. Also available is acid-resistant steel, which is resistant to chemical corrosion media (acid, alkali, salt, and so on). Metal keychains can also be made using corrosion. The corrosion resistance of the two keychains differs due to differences in their chemical composition. The shorthand for stainless and acid-resistant steel is stainless steel.


Ordinary stainless steel keychains are not normally resistant to chemical media corrosion, however, acid-resistant steel keychains are. The word "stainless steel" can refer to a single type of stainless steel or over a hundred different varieties of industrial stainless steel. Each stainless steel keychain designed performs well in its intended application. The key to success is to first understand the purpose of the keychain before determining the appropriate steel grade for the keychain.
