Sequoia Brass & Copper sells alloy 173 beryllium copper. Beryllium copper (BeCu), also known as copper beryllium, beryllium bronze and spring copper, is a copper alloy with 0.5ù3% beryllium and sometimes with other alloying elements. Beryllium copper combines high strength with non-magnetic and non-sparking qualities. It has excellent metalworking, forming and machining qualities. It has many specialized applications in tools for hazardous environments, musical instruments, precision measurement devices, bullets, and aerospace. Beryllium-containing alloys create an inhalation hazard during manufacturing due to their toxic properties.
C173 is known as a free-machining beryllium and has excellent capacity for being cold worked. Common fabrication processes for 173 beryllium copper are blanking,, drawing, drilling, forming and bending, and turning. Beryllium copper comes in bar, plate, strip, rod, shapes, tube, and wire.
