What are the introductions of metal parts?

Metal parts refer to the collective term for metal blocks, metal rods, metal tubes, etc., of various specifications and shapes made of metal materials.

Ingredient
Material of metal parts: steel and non-ferrous metals (or non-ferrous metals). Steel: The alloy of iron with a carbon content of 2% to 4.3% is cast iron, and the alloy of iron with a carbon content of generally 0.03% to 2% is steel. In Fe-C alloys, various alloying elements are purposefully added to improve the strength, hardness, wear resistance and corrosion resistance of steel. Commonly used alloying elements are Si, Mn, Cr, Ni, Mo, W, V, Ti, Nb, B, etc., forming a variety of alloy cast iron or alloy steel.

Treatment process
Anti-corrosion and anti-rust treatment: The black-boiled and blue-boiled treatment is also called phosphating treatment, which makes the metal parts have corrosion resistance and rust resistance.

Hardening treatment: The treatment method to increase the hardness of metal parts: (1) To increase the surface hardness of metal parts, use surface carburizing, and the surface color will be black after carburizing; (2) Quenching treatment can increase the hardness; (3) Vacuum Heat treatment improves the overall hardness.

Processing technology
Machining, stamping, precision casting, powder metallurgy, metal injection molding, laser processing, electric discharge processing, ultrasonic processing, electrolytic processing, particle beam processing and ultra-high-speed processing, etc. Similar to turning, milling, forging, casting, grinding, numerical control processing, CNC numerical control center are all conventional machining processing.
