Abstract
A copper-base alloy with increased melting point above 1000° C., which is resistant or immune to carburization, metal dusting and coking, resistant to oxidation at elevated temperatures. The alloy has the following composition (in weight-%): Al 4–15, Si 0.1–6, Mo 0.5–40, W 0–40, where the total of Mo and W do not exceed 40%, one or more of the group of Rare Earth Metals (REM), such as yttrium, hafnium, zirconium, lanthanum and/or cerium, up to 1.0 weight-% of each element or a total of maximum 3.0 weight-%, Cu balance and normally occurring alloying additions and impurities. A method for the alloy's production, and the alloy's use as construction components in CO-containing atmospheres, ammonia containing atmospheres, and/or hydrocarbon containing atmospheres or solid carbon containing processes, are also disclosed.
