China has been put into the equipment can produce silicon aluminum alloy ingots that silicon content is 27-70%,Guest Posting ¦300mm × 1200mm. The alloy material of the silicon content is 50%, compared with steel, the weight loss 2/3 or more, double the rate of the thermal conductivity, thermal expansion coefficient is the same. The alloy materials have been used by an Institute of Electronics, material expansion coefficient, thermal conductivity, strength, air tightness and density performance indicators have reached or exceeded the international level of similar products, and verify that the material machining, welding, surface treatment and other process performance, to meet the needs of practical application.

The history of preparing aluminum extrusion manufacturer metal materials using injection molding technology is more than 30 years in the international arena, but for a long time this technology and products are blocked and controlled. The researchers engaged in the study of the technology for nearly 20 years, has mastered the injection molding technology to produce high-performance aluminum, aluminum-silicon alloy electronic packaging materials, the core technology of the three types of new materials for high-speed tool steel, and independent intellectual property rights .

For a long time, because of its excellent conductive properties, copper and copper alloys have been to see the first choice for the manufacture of conductive materials, However, with the sharp reduction of the amount of global copper resources and increasingly exhausted, the trading price of copper is soaring. According to the metal powder exporter, the current trading price of per ton of copper reached $ 7,000, resulting in such a high investment cost prices of copper wire and other products, making the world’s electricity workers clearly recognize that improving or looking for a new electricity transmission is importance and urgency of the line.
