Phohom adopts a new explosive welding process to explode into a bimetal transition plate of copper plate and aluminum plate, which solves the problem of serious electrical corrosion in direct crimping of copper and aluminum. The contact resistance of the copper-aluminum transition joint is one-quarter of the resistance of the direct crimping of copper and aluminum.

Copper-aluminum composite transition plates are widely used in electric power, rail transit, aerospace, metallurgy, chemical industry and other fields. In the electric power industry, copper-aluminum composite transition plates are used to manufacture electrical equipment such as line towers, substations, and conductors. In the field of railway transportation, copper-aluminum composite transition plates are used in the construction of railway facilities such as tracks and sleepers. In the aerospace field, copper-aluminum composite transition plates are used to manufacture aircraft, missiles, satellites, etc. In metallurgy, chemical industry and other fields, copper-aluminum composite transition plates are used to manufacture high-temperature furnaces, reactors and other equipment, as well as to manufacture heat conductors, electronic components, etc. It can be seen that copper-aluminum composite transition plate is one of the most important materials at present. It is widely used in various industrial fields and plays an increasingly important role.
