Beryllium bronze tube, also called beryllium copper tube, is one of the commonly used copper tubes, which is a kind of Wuxi bronze tube with beryllium as the main alloy component. It contains 1.7-2.5% beryllium and a small amount of nickel, chromium, titanium and other elements. After quenching and aging treatment, the strength limit can reach 1250-1500MPa, which is close to the level of medium-strength steel. The beryllium bronze tube can be strengthened by heat treatment. It is an ideal high-conductivity, high-strength elastic material.
Beryllium bronze tube has high hardness, elastic limit, fatigue limit and wear resistance. It also has good corrosion resistance, thermal conductivity and electrical conductivity. It does not produce sparks when impacted. Commonly used brands are QBe2 beryllium bronze tube and QBe2. 5 Beryllium bronze tube, QBe1.7 beryllium bronze tube, QBe1.9 beryllium bronze tube, etc. Beryllium bronze tube has good overall performance. Its mechanical properties, namely strength, hardness, wear resistance and fatigue resistance rank first among copper alloys.
The history of China's production of beryllium bronze is almost synchronized with the former Soviet Union, the United States and other countries, but the only grades listed in the national standard are high-strength beryllium bronze QBe1.9, QBe2.0, and QBe1.7. Other high-conductivity beryllium bronzes or cast beryllium bronzes have been put into mass production according to the needs of the development of the petroleum industry and the defense industry. Wonder Copper will continue to produce beryllium bronze tubes that meet the needs of the market as the times change.

Note: In the Brush name:
- "A" represents the state of solution annealing (annealed, the alloy is in the softest state, easy to be stamped and formed, and needs to be cold worked or strengthened during the direct failure period);
- "H" stands for cold processing state (hard);
- "T" means that the material has been aging hardened by standard heat treatment (heat treatment means the state of aging strengthening heat treatment).
