QBe2 Beryllium Bronze.
QBE2 Beryllium Bronze is a beryllium bronze containing a small amount of nickel, which is an alloy with good mechanical, physical and chemical properties.
After quenching and tempering, QBE2 beryllium bronze has high strength, hardness, elasticity, wear resistance, fatigue limit and heat resistanceAt the same time, it also has high electrical conductivity, thermal conductivity and cold resistance, non-magnetic, no spark when hitting, easy welding and fiber welding, and excellent corrosion resistance in atmosphere, fresh water and seawater.
Key features: 1. QBE2 beryllium bronze has high strength, hardness and elastic limit, small elastic hysteresis, good stability, fatigue resistance, corrosion resistance, wear resistance, non-magnetic, high electrical and thermal conductivity, no sparks when impacted, easy to weld and fiber welding, and excellent corrosion resistance in the atmosphere, fresh water and seawater.
2. QBE2 high-performance copper alloy has high hardness, high wear resistance, high explosion resistance, high yield limit and fatigue limit, good corrosion resistance, high conductivity and excellent heat dissipation performance.
3. QBE2 beryllium bronze is a typical precipitation hardening alloy, which has good cold working formability after solution treatment, and can be processed into various parts with complex shapes, and the subsequent aging treatment process can produce strong precipitation hardening, and the hardness and wear resistance have been greatly improved.
4. The grading aging of beryllium bronze is an effective method to improve the mechanical properties of beryllium copper, and can overcome the shortcomings of conventional aging, which can not only improve the strengthening effect, but also reduce distortion.
