B0.6 Aluminum Bronze Plate Characteristics:
It is an electrician copper nickel alloy, its characteristic is the temperature difference electromotive force is small. The maximum working temperature is 100.
B5 Aluminum Bronze Plate Characteristics:
It is the structure of white copper, his strength and corrosion resistance are higher than copper, no corrosion cracking tendency.
B19 Aluminum Bronze Plate Characteristics:
It is copper and nickel alloy structure, with high corrosion resistance and good mechanical performance, under the hot and cold pressure good processability, under high temperature and low temperature can still maintain a high strength and plasticity, machinability is bad
B25 Aluminum Bronze Plate Characteristics:
It is structural copper-nickel alloy, it has high mechanical properties and corrosion resistance, and it is well processed under hot and cold conditions. Due to its high nickel content, its mechanical properties and corrosion resistance are higher than that of B5 and B19.
B0.6 Aluminum Bronze Plate Application:
It is used to make a non - long conductor for special thermocouple (platinum-platinum-rhodium-rhodium-hot couple).
B5 Aluminum Bronze Plate Application:
Used as corrosion resistant parts for ships
B19 Aluminum Bronze Plate Application:
Precision instrument parts, metal mesh and chemical corrosion resistant chemical machinery parts, medical instruments and COINS for work in neat, fresh water and seawater.
B25 Aluminum Bronze Plate Application:
Used for corrosion resistant parts in steam and seawater, metal tubes and condensing tubes that work under high temperature and pressure.
