What Are Commonly Used Raw Material For Metal Stamping Parts

Aluminum: the commonly used specifications are AL1100, AL3003, AL5052. Aluminum is easy to deform and is generally used in cap products, draw parts.

At present, we use copper, aluminum, stainless steel, iron, copper-iron alloy, low carbon steel, etc. Generally, the thickness of copper is not 0.1mm-2.0mm, and according to the multiple of 0.1, it is normal material. The starting quantity of unconventional material is generally 1 ton, and the cycle is 30 days.

Pure copper (red copper): pure copper is a rose-red metal, the surface of the formation of copper oxide film, the appearance of purple, it is called red copper. General copper thickness tolerance is +/-0.2mm, general hardness requirements H, 1/2H, 3/H, M.

Beryllium copper: C17200 is a kind of imported beryllium copper, known as "the king of non-ferrous metals", used for various kinds of micromotor brushes, switches, relays, connectors, temperature controllers, and all kinds of shrapnel with high strength, high elasticity, high hardness, and high abrasion resistance.

Phosphorous bronze: common as C5191, highly corrosive.

Copper Nickel Alloy: C7541 C7521 C7701 are commonly used for shield cover.

Type of stainless steel: SUS301, SUS304 is the most commonly used, which are suitable for elastic use, high carbon content, high hardness, not easy to be elastic, and fatigue. Poor ductility and difficulty to stretch.
