Automotive electronic components are an important consumer of beryllium copper strips. One of the main uses is automotive engine compartment components, such as engine control systems. These parts have higher operating temperatures and severe vibrations. In North America, Europe, Japan, and South Korea, the amount of electronic components is increasing, which is the result of manufacturers' continuous increase in new car functions.
Automotive contactor consumption is another major market for beryllium copper alloys in the United States.
The furnace charge is evenly fed into the crucible through the hopper through the electromagnetic vibrator. The vacuum induction circuit has a capacity of up to 100 tons, but the furnace capacity for melting beryllium copper alloys is generally 150 kg to 6 tons. The operation sequence is as follows: firstly load nickel, copper, titanium and alloy wastes in the furnace, raise the temperature after vacuuming, refining for 25 minutes after the materials are melted, and then add beryllium-copper intermediate alloy to the furnace, and stir the furnace after melting. .
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. It is an irreplaceable material for submarine cable repeater structures. In sulfuric acid medium: The annual corrosion depth in sulfuric acid (room temperature) of less than 80% concentration is 0.0012-0.1175mm, and the corrosion is slightly accelerated if the concentration is greater than 80%.
