Which raw materials is better between stainless steel and brass

Publish time: 30 Nov 22

Recently, many customers have asked me which material is better: brass or stainless steel, the two commonly used raw materials for producing screws. As a manufacturer with 20 years experience in screw production, we will take you into the world of brass and stainless steel today:

1.Material, brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called common brass. Brass is often used in the manufacture of valves, water pipes, air conditioning inside and outside the machine connection pipe and radiator. Stainless Steel is short for stainless acid resistant steel, air, steam, water and other weak corrosion medium or stainless steel is called stainless steel; And the chemical corrosion resistant medium (acid, alkali, salt and other chemical erosion) corrosion of steel called acid resistant steel. Because of the difference in the chemical composition, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to the corrosion of chemical media, while acid-resistant steel is generally rustproof;

2.Hardness: stainless steel is strong and durable, corrosion resistance is not easy to oxidize, not easy to change color. Stainless steel is made of advanced stainless steel precision manufacturing, from the material essence to solve the traditional copper zinc alloy easy oxidation discoloration defects. Brass is also strong and durable, and it has antiseptic effects.

3.Processing accuracy: brass parts are easy to cut, tool wear is very little, tolerance can achieve good control, can achieve higher accuracy, mass production parts change precision change is smaller than mine. Stainless steel processing is relatively difficult to process, cutting tool wear, mass production size is easy to change. When the stainless steel will be polished, the surface of the light height can reach a complete mirror, brass can only resemble a flat mirror.

Therefore, I think it is necessary to take comprehensive consideration of comprehensive use and choose more suitable raw materials according to different usage scenarios and product requirements.
