Automotive electronic components are an important consumer of beryllium copper strip, and one of the main uses is in automotive engine compartment parts, such as engine control systems, which operate at higher temperatures and are subject to severe vibrations. Vehicles produced in North America, Europe, Japan, and South Korea are all showing an increase in the use of electronic components as a result of manufacturers continuing to add new features to their vehicles. In the United States, automotive contactor consumption is another major market for beryllium copper alloys.
The charge is evenly fed into the crucible through the hopper through the electromagnetic vibrator. The capacity of the vacuum induction circuit can reach 100 tons, but the capacity of the furnace for melting beryllium copper alloy is generally 150 kg to 6 tons. The editor of the Dongguan beryllium-nickel-copper supplier said that the operation sequence is: first, put nickel, copper, titanium and alloy scraps in the furnace in sequence, vacuumize and heat up, and refine the materials for 25 minutes after melting, and then add them to the furnace. Beryllium-copper master alloy, after being melted, stirred and released.
Corrosion resistance rate of beryllium copper alloy in seawater: (1.1-1.4)×10-2mm/year. Corrosion depth: (10.9-13.8)×10-3mm/year. After corrosion, there is no change in strength and elongation, so it can be maintained in seawater for more than 40 years, and it is an irreplaceable material for submarine cable repeater structures. In sulfuric acid medium: in sulfuric acid with a concentration of less than 80% (room temperature), the annual corrosion depth is 0.0012-0.1175mm, and the corrosion is slightly accelerated when the concentration is greater than 80%.
