Where a timber joint has to be held and later cut, aluminium nails are used as it is a softer material, reducing the impact on the saw blades and machinery of the joiner/ manufacturer. This material, being softer, cannot be made into long lengths of fastener or be driven into some harder species of timber. However, the lighter properties of aluminium nails are an advantage and also offer better rust resistance than galvanised nails. Identified in SKU codes as AL or ALU.
