QBe2.0铍青铜 耐热性铍青铜
QBe2.0 beryllium bronze alloy is mechanical, physical, chemical good comprehensive properties of an alloy, beryllium bronze material after quenching tempering, has high strength, flexibility, abrasion resistance, fatigue resistance and heat resistance, beryllium bronze at the same time also has the very high electrical conductivity, thermal conductivity, cold resistance and nonmagnetic, beryllium copper material no spark when touch attack, beryllium bronze easy to welding and brazing, in the atmosphere, fresh water and seawater corrosion resistance is wonderful, beryllium copper alloy is a kind of rare. Beryllium bronze strip can make electronic connector contacts, make all kinds of switch contact, make key parts and components, such as the film plate, diaphragm, bellows, spring washer, electric brush and commutator, electric plug, switch, contacts, clock parts, audio components etc.
不含氧也不含任何脱氧剂残留物的纯铜。但实际上还是含有非常微量氧和一些杂质。按标准规定，氧的含量不大于0.003%，杂质总含量不大于0.05%，铜的纯度大于99.95%。根据含氧量和杂质含量，无氧铜又分为一号和二号无氧铜。一号无氧铜纯度达到99.97%，氧含量不大于0.003%，杂质总含量不大于0.03%；二号无氧铜纯度达到99.95%，氧含量不大于0.003%，杂质总含量不大于0.05%。无氧铜无氢脆现象，导电率高，加工性能和焊接性能、耐蚀性能和低温性能均好。各国对于含氧量的标准也不完全相同，存在一定的差异。OFC（无氧铜）：纯度为99.995% 的金属铜。一般用于音响器材
