Clean the surface of the beryllium copper billet that meets the required width; conduct the first pickling of the beryllium copper billet; put the pickled beryllium copper billet into a heating furnace for heating at a heating temperature of 800-900C°; medium rolling: The heated beryllium copper billet is transferred to the rolling mill for intermediate rolling to obtain an intermediate copper plate; the intermediate beryllium copper plate is annealed at 800-850C°; the intermediate beryllium copper plate is pickled for the second time; drying; finishing rolling: The intermediate beryllium copper plate after the second pickling is moved to a rolling mill for finishing rolling to obtain a finished beryllium copper plate. The process effectively improves the efficiency and quality of the hot rolling of the beryllium copper sheet, and overcomes the surface defects of the beryllium copper sheet and the side bending of the beryllium copper sheet and strip.
Production Technology Advantage
All products of the company are made of high-quality new materials, advanced production equipment, and vacuum melting furnaces. The metal materials are smelted under vacuum conditions, which can achieve the effect of high-temperature smelting and avoid oxidation of metal and oxygen in the air. Function, quality is more guaranteed;
20MN double-action reverse extruder;
Equipped with comprehensive testing equipment such as universal testing machine, direct reading spectrometer, etc., to strictly control the quality and inspect layer by layer.

Note: In the Brush name:

• “A” represents the state of solution annealing (annealed, the alloy is in the softest state, easy to be stamped and formed, and needs to be cold worked or strengthened during the direct failure period);
• “H” stands for cold processing state (hard);
• “T” means that the material has been aging hardened by standard heat treatment (heat treatment means the state of aging strengthening heat treatment).
