Copper is a metal that is soft and easy to process, and has the characteristics of passing electricity well, transmitting heat well, and having good corrosion resistance. It has been used in a wide range of fields such as money, electric wires, and building materials since ancient times. Beryllium copper alloy, which is made by adding a few percent of beryllium to copper, has the high strength comparable to special steel and the excellent spring property while making good use of the good properties of copper. It can be said that the material.
Today, it is widely used as a conductive spring material for automobiles, mobile phones, personal computers, communication devices, etc., and contributes to high reliability and miniaturization.
Our beryllium copper products comply with the European RoHS directive.
The European RoHS compliance mark is posted on the test inspection report and catalogs of the product, but the compliance evaluation is based on our internal standards.

- Beryllium copper alloy 172 (BeCu) is one of the highest strength copper alloys, ideal for parts that require high strength and electrical conductivity. It has excellent corrosion and galling resistance. Beryllium copper 172 is also non-magnetic and has a very low permeability, making it a suitable choice for magnetic housings. BeCu 172 has a machining cost factor of 3.0 when compared to steel 12L14. It is good for soldering, brazing, forging, welding, and hot and cold working. BeCu 172 can be annealed.
- Beryllium copper alloy 173 (BeCu) is a free-machining copper alloy, ideal for parts that require very high strength and stiffness. It has excellent electrical conductivity and is one of the highest strength copper alloys. Beryllium copper is also suitable for environments that require high corrosion resistance, such as marine environments. BeCu 173 has a machining cost factor of 1.0 when compared to steel 12L14, making it a better economic choice than BeCu 172. It is good for soldering, brazing, welding, and hot and cold working, but is not ideal for forging. BeCu can be annealed.
- Beryllium copper alloy 175 (BeCu) is a free-machining copper alloy, ideal for parts that require high strength and stiffness. It has excellent electrical conductivity. Beryllium copper is also suitable for environments that require high corrosion resistance, such as marine environments. BeCu 175 has a machining cost factor of 1.5 when compared to steel 12L14. It is good for soldering, brazing, welding, and hot and cold working, but is not ideal for forging. BeCu 175 can be annealed.
- Tellurium copper alloy 145 (TeCu) is considered a free-machining copper alloy, ideal for parts that require extensive machining, corrosion resistance, or high conductivity. It produces short, clean chips that are easily removable. Tellurium copper machines more quickly and efficiently than pure copper. TeCu has a machining cost factor of 0.8 when compared to steel 12L14. It is good for hot and cold working, forging, brazing, and soldering, but is not ideal for welding. TeCu can be annealed.

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).
