The parts are normally delivered "slab", with smooth, smooth-looking surfaces, with two small witnesses (attachments) easily removable.
Copper alloys (brass, bronze and nickel silver) can be easily soldered with tin or welded with silver alloy, polished with special abrasive wheels, or with tumbling and vibrating systems.
EXELLA materials 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 400 Vickers).
Stainless steels with mirror polished surface (ba) are also available.
