What kind of finish can I get from precision cast parts?
The parts are normally delivered with smooth surfaces, with an opaque satin finish, with a small residue from the injection channel.
Copper alloys (brass, bronze and nickel silver) can be easily soldered with tin or welded with silver alloy, mirror polished with special abrasive wheels, or with systems such as tumbling and vibrating.
EXELLA materials do not contain lead and cadmium, do not undergo acid treatments and are tested to accept all the most common galvanic treatments (copper plating, nickel plating, silver plating, gilding, rhodium plating, etc ...).
Beryllium copper lends itself to thermal treatments of solubization and aging, to obtain surprising elasticity and hardness characteristics (even over 300 Vickers).
