Classification (category) and Uses of Beryllium Alloys.

According to different processing methods, beryllium bronze is divided into two categories: processing alloys and casting alloys (referred to as processing alloys and casting alloys). Beryllium bronze processing alloys are generally made into plates, strips, tubes, rods, wires, etc. by pressure processing. The alloy grades are Be-A-25; BeA-165; BeA-190; BeA-10; AeA-50, etc. .
Beryllium bronze casting alloys are alloys used to manufacture parts by casting methods. Beryllium bronze is divided into high-strength alloys and high-conductivity alloys according to the content of beryllium.

Beryllium bronze processing alloys are generally made into plates, strips, tubes, rods, wires, etc. by pressure processing. The processing of these products is a complex process. The general process is: according to the requirements of different uses, get the composition of the required alloy. Be and Co are calculated according to a certain burning loss rate, and are melted in a graphite crucible induction furnace. The rough slab is made by semi-continuous flowless casting and other methods. After double-sided milling (or single-sided milling), the slab is subjected to hot rolling and blanking, and then hot rolling, finishing rolling, heat treatment, pickling, edge trimming, Welded and rolled. The heat treatment is carried out in a nitrogen-protected air-floating continuous furnace or a bright bell-type annealing furnace. Rods and tubes are hot-extruded after casting billets, then drawn, heat-treated, and then machined into products.

The main uses are connectors, integrated circuit sockets, switches, relays, micro motors and other conductive spring materials. Because beryllium bronze rolled products have strength, excellent elasticity and electrical conductivity that other copper alloys do not have, they are also used in workstation notebook computers, integrated circuit memory card boards, mobile phones, automobiles, micro sockets, IC sockets, and micro switches. Micro motors, relays, sensors and other fields of household appliances.
