Beryllium-Copper Sheets & Plates

C17000 is a part of the “gold alloys” because of the shiny luster imparted by the substantial amount of beryllium present (~12 at. %). The gold alloys are the high-strength beryllium-coppers because they can attain yield strengths ranging from approximately 205 to 690 MPa (30 to 100 ksi) in the age-hardenable condition to above 1380 MPa (200 ksi) after aging. Conductivity ranging from about 20% to higher than 30% IACS is obtained in wrought products depending on the amount of cold work and the heat treatment schedule.

Typical uses: bellows, bourdon tubing, diaphragms, fuse clips, fasteners, lock washers, springs, switch parts, roll pins, valves, welding equipment.

C17200 is manufactured to provide a combination of high strength and hardness properties coupled with superior thermal properties. This range of properties makes C17200 the premier material for copper alloy molds and a wide range of other applications from oil and gas to aerospace.

C17500/C17510 offer a combination of high electrical and thermal conductivity with good strength compared to most copper based alloys. C17500 alloy is the mirror image of alloy C17510 in terms of its properties and characteristics. The alloys differ in that C17500 specifies a cobalt alloying addition (2.40-2.70 %) and alloy 17510 specifies a nickel alloying addition (1.40-2.20 %), but their performance are the same. Typical uses: fuse clips, fasteners, springs, switch and relay parts, electrical conductors and welding equipment.

MoldMax provides strength and wear resistance similar to that of many tool steels and a thermal conductivity that is three to four times greater than steel and comparable to aluminum. MoldMad is typically specified for full cavity and core inserts, blow mold pinch offs, neck rings and handle inserts; cavity and core sub inserts; injection mold components; and hot runner system injection nozzles and manifolds.
