Abstract: An aluminum-cobalt-chromium-iron-nickel-silicon alloy has atomic percentages of 4-12 at % aluminum, 15-25 at % cobalt, 25-35 at % chromium, 4-8 at % iron, 15-25 at % nickel, 10-25 at % silicon, wherein the atomic percentage of aluminum plus silicon is between 18-32 at %. The disclosure applies the alloy design to develop a low-aluminum Al—Co—Cr—Fe—Ni—Si alloy composition, and has high-temperature hardness, high wear resistance, corrosion resistance and high temperature oxidation resistance.
