Selection of raw materials for metal stamping terminals


The widespread use of the electronics industry is increasingly changing the production and lifestyle of human beings. As metal stamping terminal in electronic products, its precision and requirements are of paramount importance in electronic products.

Selection and differentiation of hardware stamping terminal product materials:
A: Common materials are divided into: C5210 C5191 C2680 SUS301 SUS304 SUS201 SPCC C1100
B: Each category is divided according to the hardness: H EH SH 1/2H 3/4H
C:: Common phosphor bronze material is: C5210—H/EH C5191—H/EH

Phosphorous bronze and copper are elastic and strong, have good electrical conductivity, are not easy to heat, ensure safety and have strong fatigue resistance. Tin-phosphor bronze jack reed hard-wired electrical structure, no rivet connection or frictionless contact, can ensure good contact, good elasticity, smooth dialing.

Common green (yellow) copper material is: C2680-H/EH Copper has: brass is golden yellow, good toughness, good electrical conductivity, low resistance to electrical properties.

Common stainless steel material: SUS301—1/2H SUS304—3/4H SUS304 stainless steel: good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, no heat treatment hardening, non-magnetic .
