Beryllium is used as an alloying agent in the production of beryllium-copper because of its ability to absorb large amounts of heat, and resist oxidation when exposed to air. Beryllium-copper alloys are used in a wide variety of applications because of their electrical and thermal conductivity, high strength and hardness, nonmagnetic properties, along with good corrosion and fatigue resistance. These applications include the making of spot-welding electrodes, springs, non-sparking tools and electrical contacts. It is, however, brittle, chemically reactive, expensive to refine and form for this reason it is imperative to get the job done right the first time. With over 50 years of plating experience we have fine-tuned our process to a superior result. Some exotic metals are characterized by their extremely high melting points, which range well above those of iron, cobalt, and nickel. These are sometimes called refractory metals. Because of these high operating temperatures the adhesion between the base metal and plated metal has to be very reliable. The most extensively used of these metals are tungsten, tantalum and molybdenum.
