ALUFONT®-47 is an extremely strong and hardenable aluminium–copper–casting alloy for use in sand and coquille casting. The achievable mechanical properties can be varied through different heat treatment conditions. During full hardening (T6) the alloy tends towards tension crack corrosion.
Like all alloys of type AlCu4TI, ALUFONT®-47 is difficult to cast and is therefore suitable for simple cast parts subject to extreme strength requirements. ALUFONT®-47 is highly weldable, while polishing and machinability are excellent. Due to the high copper content, corrosion resistance of the alloy is low. No corrosion problems occur in normal areas of use in engineering, although the application of a dense and resistant protective coating is recommended when using the material in conditions that promote corrosion. |
