Foundry is a production process in which pattern is used to prepare mould by ramming suitable prepared sand. The pattern when withdrawn leaves a cavity (shape) in which molten metal is poured into it, after solidification it is extracted and fettled to suit the purpose it is made to serve. This work x-rayed into the foundry production process of Motor cycle clutch handle produced by Sand and Die casting processes, tested for hardness comparatively with the imported one. Hardness is the property of a material that enables it to resist plastic deformation, usually by penetration. It is not an intrinsic material property dictated by precise definition in terms of fundamental units of mass, length and time. It is a property value defined in terms of measurement procedure. The test of the casts (Aluminium alloy motorcycle clutch handle) was carried out using Vickers micro-hardness tester and the result obtained compared with the result of the imported clutch handle made from the same aluminium alloy. These result showed that the average hardness value for Sand cast specimen is 127.65 Hv, for Die cast specimen is 124.25 Hv and that of the imported cast handle is 89.05 Hv, indicating clearly that locally produced aluminium alloy motor cycle clutch handle can equally be used in the motorcycle construction.
