What is a C17500
C17500 is a high conductivity beryllium bronze alloy with the following characteristics:
Medium yield strength: The value after aging treatment is 980MPa.
Conductivity: 45% -65% of the conductivity of pure copper.
Comprehensive performance: It combines high strength, high rigidity, high wear resistance, as well as good corrosion resistance, thermal conductivity, and conductivity.
Application field: Widely used in the manufacturing of precision mechanical parts such as elastic components, valve springs, conductive springs, contactors, cutting tools, high-voltage electrical appliances, etc.
Composition elements: Contains copper (Cu), cobalt (Co), and beryllium (Be), with copper content of about 65%, cobalt content of about 25%, and beryllium content of about 10%.
These characteristics make C17500 one of the irreplaceable materials in applications that require heat dissipation and current carrying.

C17500 applicationr
Product specific situation C17500 beryllium cobalt copper performance: Jin Guang C117500 beryllium cobalt copper has good processing ability and high thermal conductivity. In addition, beryllium cobalt copper C17500 also has excellent welding, corrosion resistance, polishing, wear resistance, and adhesion resistance. It can forge parts of various shapes, and the strength and wear resistance of beryllium cobalt copper C17500 are better than the physical properties of chromium zirconium copper alloy. C17500 Beryllium Cobalt Copper Application: C117500 Beryllium Copper is a medium strength and high conductivity component, such as fuse fasteners, springs, connectors, resistance spot welding heads, seam welding rollers, die-casting machine heads, plastic forming molds, etc. Application of Jinguang C17500 Beryllium Cobalt Copper in Mold Manufacturing Industry: Beryllium Cobalt Copper C17500 is widely used for manufacturing inserts and cores in injection molds or steel molds. When used as an insert in plastic molds, C17500 beryllium cobalt copper can effectively reduce the temperature of the heat concentration zone, simplifying or eliminating the design of cooling channels. The extremely excellent thermal conductivity of Jin Guang beryllium cobalt copper is about 34 times superior to that of mold steel. This characteristic ensures rapid and uniform cooling of plastic products, reduces deformation, unclear appearance details, and similar defects.
In most cases, it can significantly shorten the production cycle of products.
Therefore, beryllium cobalt copper C17500 can be widely used in molds, cores, and embedded parts that require rapid and uniform cooling, especially for high thermal conductivity, corrosion resistance, and good polishing requirements.
1) Blow molding: Insert parts for the clamping part, stiffening ring, and handle.
2) Injection mold: The inserts in the corners of the mold, core, and TV casing, as well as the converging chamber of the nozzle and hot runner system. |
