Frequently Asked Questions

What Is GRCop-42?

GRCop-42 is an advanced copper alloy powder developed by NASA exclusively for use in the aerospace industry. It’s a part of a group of GRCop alloys that is suitable for additive manufacturing by Powder Bed Fusion (PBF), specifically Selective Laser Melting (SLM). It has a high-strength dispersion and high conductivity

What Are the Properties of RocketPowder?

RocketPowder is composed of rhenium and tantalum for enhanced strength and high-temperature stability at 1400 ºF and outperforms traditional copper alloys like CuCrZr in terms of creep resistance and thermal conductivity. It also exhibits high-strength dispersion, high conductivity, and excellent oxidation and blanching resistance.

Where Is GRCop-42 Used?

GRCop-42 is used in high strength and high heat flux applications in the aerospace industry for complex components such as liquid rocket engine combustion devices, nozzles, and throat inserts which can withstand the extreme temperatures and pressures experienced during rocket propulsion. It’s also valuable for use in hypersonic vehicles and thermal management systems.

What Is the Difference Between GRCop-42 and 84?

GRCop-42 has improved conductivity and limited reduction in strength over GRCop-84 along with a simplified powder atomization. But GRCop-42 copper alloy powder displays lower mechanical properties like strength, for higher thermal conductivity, resulting in a lower wall temperature. However, both alloys can operate at temperatures up to 800°C, leaving behind all other copper-based alloys in the 500-700°C range.
