银(Ag) 30%冷加工

银(Ag)是一种白色的闪光，在非常薄的薄膜蓝绿色半透明，在规则的八面体(立方密度最大的球体包装)结晶金属。银是仅次于黄金的延展性最强的金属，可以被拉成直径为0.008毫米的金属丝，并轧制成最薄的薄膜。银是所有金属中导电率和导热率最高的，而且反射率最好。对氧和碱，银是非常稳定的在正常和高温。相反，它对硫的亲合力增强。在银制品上形成的硫化合物使银变黑。硝酸将其溶解形成硝酸银。溴化银在光的作用下分解。然而，它在含硫的大气中形成硫化银，这对于小的接触力来说是非常令人不安的，因为它们发生在新闻和信息技术中。对于较大的接触力，因为它们在动力工程中很常见，但硫化银不会干扰。 Silver is relatively soft and is hardened in a manner similar to gold by alloying with Au, Pt, Pd, Cu, Zn, Sn, Cd, Si, Mg or Mn. With not too large proportions of the hardening metals, easily deformable alloys are obtained. Ag is also used as a coating material, it is plated on brass, copper and steel or a silver layer is electroplated (silver plating). Application: In the chemical technique for porous disks in filtration, as catalyst in catalysis. As a fusible conductor is pure silver (Ag1000) due to its aging resistance, its oxide-free surfaces and good solder wettability, its perfect contact and the fact that pure silver has a small melting integral, low heat of fusion (nimble fuses), very well suited for low-voltage and High-voltage high-performance fuses, used for power converter fuses and for miniature fuses. Silver is the most commonly used contact material, but tends to weld and has relatively high material migration. Ag is very ductile, sulfur-sensitive and oxidation-resistant up to 180 ° C. It is machinable, roll-cladable, electrodepositable and can be separated from the gas phase.
