Cast iron should be used for components which must be strong in compression. It is recommended for machine beds and frames. Wrought iron is recommended for components where tensile strength is required; for example, crane hooks and railway couplings. Mild steel should be used for components which must be strong in shear; therefore it is recommended for rivets and bolts. Medium carbon steel is recommended for components where impact strength is required; for example, axles and hammer heads.

Soldering is recommended for making connections on electrical circuits, but it should never be used where strong joints are required. For permanent joints between two dissimilar materials like nylon and metal, it is advisable to use adhesives. For temporary jobs, like fitting a maintenance cover, screw-fastening should always be used. Riveting is recommended for permanent sheet-metal joints such as outer casing fitting. Although welding should always be used for steel support girders, brazing can be used for medium-sized joints where strength is required; for example the joint between the base and body of a hydraulic jack.
