Beryllium copper raw material is copper alloy with beryllium as the main alloying element, also known as beryllium bronze, high beryllium copper, hardness is higher than brass, copper content is lower than brass, copper content is very small. Good wear resistance, good elasticity, and relatively good electrical conductivity.
In the industry, beryllium copper products are relatively rare, and there are not many molds designed with beryllium copper structure in the mold. In order to let everyone fully understand the mold structure of beryllium copper, today we will popularize the knowledge of beryllium copper mold structure.

“Self-moistening” of beryllium copper
Beryllium copper is as easy as bronze to produce a thin adhesive layer when it is rubbed with steel, which adheres to the surface of the steel and offsets the friction with the steel. We call it “self-lubricating”.
So we don’t have to worry about the beryllium copper adding the thimble, it will be worn or seized due to the frequent friction of the thimble. The traditional ball bearing is limited by the material and structure, and cannot be used in some high temperature, high pressure and high humidity occasions. Hou beryllium copper is the best bearing material.

Application of beryllium copper material
Although beryllium copper has self-lubricating properties on smooth surfaces such as steel, it cannot withstand the scratching of glass fibers, so it is not suitable for friction mold cores that will be fiber-reinforced with PBT. It can only be like the insert inside the round core, not plastic In the case of direct friction.
If beryllium copper is really required to directly rub the plastic, the formed mold core must be coated with alumina, silicon carbide and other ceramic surfaces.
Because beryllium copper is self-lubricating, it is not necessary to add any processing agent during traditional turning ‘milling’ drilling.

Advantages of beryllium copper material
Beryllium copper has better heat dissipation and the main reason for its beautiful texture is that beryllium copper has excellent thermal conductivity, good mechanical properties and good hardness.
It is generally used in areas where the injection temperature of the product is high, it is not easy to use cooling water, and the heat is concentrated, and the product quality requirements are relatively high!
Beryllium copper is most used in products with high requirements on appearance and complex appearance. The main advantage is that there is no need to save mold, and the fluidity is good.

Precautions for the use of beryllium copper materials
The thermal conductivity of beryllium copper is seven times that of steel, so it is especially suitable for heat conduction in small and high temperature places (the effect of heat pipe is better, but the shape of the heat pipe is limited, and it cannot be processed by us like beryllium copper).
The hardness of beryllium copper is HRC25~40 degrees, which is enough to withstand injection and structural pressure, but beryllium copper is also quite brittle, so it should not be hit with a hammer when using it, otherwise it will easily crack.
