Description of RWMA Class 20 Al2O3 Dispersion Strengthened Copper Alloy:
Cuberyllium C15760(RWMA Class 20) is a high alumina content grade of dispersion strengthened copper. It consists of a pure copper matrix containing finely dispersed sub-microscopic particles of Al₂O₃ is thermally stable so that it acts retard recrystallization of the copper. Consequently, significant softening does not occur as the result of high temperature exposure. Along with superior strength retention, thermal and electrical conductivities are higher than conventional copper alloys.
Cuberyllium C15760, tihs grade is available as rod and bar stock, strip and strip reroll, and large rounds. Most forms are available with or without an oxygen free copper cladding. Unless specified as "declad", Cuberyllium is supplied with cladding.
 
Chemical Composition of RWMA Class 20 Al2O3 Dispersion Strengthened Copper Alloy:
Product Grade: CUBERYLLIUM ®-C15760 (RWMA Class 20)

Aluminum 0.60% by wt. as Al₂O₃
Cu: Balance

 
Typical Physical Properties of RWMA Class 20 Al2O3 Dispersion Strengthened Copper Alloy:

Melting Point 1083°C 1981°F
Density 8.81 g/cm3 at 20°C 0.318 lbs./in3 at 68°F
Electrical Conductivity (σ) 0.452 μ Ω-cm at 20°C 78% IACS at 68°F
Thermal Conductivity (K) 322 W/m/K at 20°C 186 Btu/ft2/ft/hr/°F at 68°F
Electrical Resistivity (ρ) 2.21 μ Ω-cm at 20°C 13.29 Ω circular-mil/ft. at 68°F
Coefficient of Thermal Expansion 16.6 μm/m/°C (20-150°C) 9.2 μin/in/°F (68-300°F)

Applications of RWMA Class 20 Al2O3 Dispersion Strengthened Copper Alloy:
Cuberyllium C15760 is primarily designed for applications requiring the highest elevated temperature strength coupled with relatively high electrical and thermal conductivities. It exhibits a high degree of resistance to softening after exposure to elevated temperatures. Cuberyllium C15760 has sufficient cold working charateristics for heading, extrusion and some drawing and rolling operations.

Recommended for:

 Resistance welding electrodes
Welding electrodes
Solder gun tips and MIG contact tips

For applications requiring brazed joints and /or extended high temperature exposure in hydrogen-containing atmospheres or vacuum, low Oxygen is availbale and recommended.
