products description
This is a metal casting part, made of aluminum alloy. It be a component of a mechanical device, possibly an engine or transmission housing part.
Function: It serves as a casing or cover, providing protection and structural support for internal components, also helping to contain fluids (like oil) and ensure proper operation of the machinery it belongs to by enclosing and safeguarding moving parts.
