Cr-rich al alloy with high compressive and shear strength

A process for producing a component from a Cr-containing Al alloy, comprising:

• forming a Cr-containing Al alloy consisting of:
• 0.5-20.0 wt %, or 1.0-10.0 wt %, or 2.0-8.0 wt %, or 4.0-6.0 wt %, of Cr;
• 0.0-6.0 wt %, or 0.3-5.0 wt %, or 0.8-3.0 wt %, or 1.0-2.0 wt %, of at least one element selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, Mo, W, Mn, Fe, Co and Ni, where up to 3 elements selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, Mo, W, Mn, Fe, Co, and Ni are present;
• 0.0-6.0 wt %, or 0.3-5.0 wt %, or 0.5-3.0 wt %, or 0.7-2.0 wt %, of at least one element selected from the group consisting of Sc, Y and lanthanoids;
• 0.0-2.5 wt %, or 0.2-2.0 wt %, or 0.4-1.5 wt %, or 0.6-1.0 wt %, of at least one element selected from the group consisting of B, Ga, In, C, Si, Ge, Sn, and Pb;
• and as a balance Al and unavoidable impurities, where percentages by weight add up to 100 wt % in the Cr-containing Al alloy, and
• forming the component.
