Some questions about Beryllium Copper 50

Beryllium copper is a copper matrix alloy material with beryllium as the main element added. Its scope of application is to use beryllium copper material under the requirements of high thermal conductivity, high hardness and high wear resistance. Beryllium copper can be divided into strips, plates, rods, wires, and tubes in the form of materials, and if the physical function of beryllium copper is used to distinguish, generally speaking, there are three kinds.

1: High elasticity 2: High thermal conductivity, High hardness 3:

The electrodes are used with high hardness and high wear resistance.

In a larger scope, physical materials are generally divided into two types; 1- Structural materials 2- Functional materials, functional materials refer to materials that exhibit special properties other than mechanical properties, such as electricity, magnetism, light, biology, chemistry, etc. In this sense, beryllium copper should belong to structural materials, and beryllium copper should be a light metal compared with other brass and red copper.

At the request of the customer, we focus on the beryllium copper forging die material here.

Beryllium copper forging mold material is applied to the mold with its high thermal conductivity, high hardness, delicate texture depiction, high finish, etc., but the cost of beryllium copper is high, and the mold factory is often only used in places that need high heat dissipation effect, thus limiting the wide range of applications of beryllium copper. The manufacturing process of beryllium copper blocks is similar to that of other coppers, with only a few differences.

Beryllium copper processing generally has; Beryllium raw material ore - crushing - grinding - screening - making beryllium oxide - reducing metal beryllium - melting - proportioning - solid melting - forging processing - embryo opening and other links, beryllium copper bar formation generally has two kinds of drawing and extrusion, I will not talk much here.

Because of the high cost of beryllium copper, general mold manufacturers require theoretical weight calculation to be used as a cost reference. Therefore, I have calculated the weight of the beryllium copper mold material as follows:

The formula for calculating the weight of beryllium copper blocks:

Length, width, thickness and density (number of pieces 1000000; You can get the theoretical weight of beryllium copper block, because it is to be converted into kilograms, so the unit conversion should be carried out later, and it can be directly divided by 1000000.

The weight calculation formula of beryllium copper bar stock:

The square of the radius Length Density (number of pieces 1000000 ; The theoretical weight of beryllium copper bar stock can be obtained.

The above calculation of the weight of beryllium copper does not take into account the machining allowance, and the actual wire cutting method generally leaves a margin of 1-2 mm.

The landlord of this place can take a look, and contact the author, there should be a harvest.
