C15760, RWMA Class 20, AWS J1.3, Glidclop™ Al-60
C17515, RWMA Class 21, AWS J1.3, Glidclop™ Al-15
C15725, RWMA Class 22, AWS J1.3, Glidclop™ Al-25
Overview:
C15760 / Glidclop™ Al- 60 is designed for applications needing the highest elevated temperature strength along with relatively high electrical and thermal conductivity. It maintains a high degree of resistance to softening after being exposed to elevated temperatures. It has sufficient ductility for further cold working such as heading, drawing, and rolling operations. Available with or without oxygen free copper cladding. The properties are consistent with RWMA Class 20 specifications. Aluminum 0.60%, Copper balance. Typical usages are listed below.
C17515 / Glidclop™ Al-15 is designed for applications needing the highest electrical and thermal conductivities along with good, elevated temperature strength. Excellent for cold working and can be drawn into fine wire or rolled into thin sheets. Available with or without oxygen free copper cladding. The properties are consistent with RWMA Class 21 specifications. Aluminum 0.15%, Copper balance.
C15725 / Glidclop™ Al-25 is designed for applications needing high electrical and thermal conductivity along with good, elevated temperature strength. Excellent cold working characteristics and can be drawn into fine wire or rolled into thin sheets. Available with or without oxygen free copper cladding. The properties are consistent with RWMA Class 22 specifications. Aluminum 0.25%, Copper balance.
