Electronic products in the conductor connection parts of the metal shrapnel 95% is the use of copper materials (brass, phosphorus copper, red copper, copper, beryllium copper), today only three commonly used in the shrapnel of copper, and some electronic products in the safety regulations on the designation of copper must be used in the material, and the material in the amount of copper.
In the face of practical design selection, some inexperienced engineers are blindfolded, do not know that the copper is good, do not be smart to think that the copper is anyway get up and say, do not recommend that, because it will be spanked; first of all, different copper performance, such as leading to the test can not be passed or other problems to change the material that the mold may be scrapped, or lead to delays in the product project is not good; and second is the Costs are different, directly affect the cost of the product, money is the boss’s life, a low-grade products you use the top materials to get up. Then the consequences of your own discretion!
Key performance distinction:
1.) brass: good toughness, soft, hardness is not high, elasticity is not strong. But his bending performance is good. (Commonly used grades C2680, C26000, etc.),
Low cost.
2.) phosphorus copper: toughness is poor, good hardness, elasticity, good conductivity (such as socket shrapnel is basically with this one.
Commonly used brand C5191, C5071, etc.), medium cost.
3.) Beryllium copper: hard, elasticity is the best. But the highest cost.
