Iron is the most commonly used metal in hardware metalwork due to its strength, durability, and affordability.

Metalwork in hardware serves various purposes, including decoration, protection, and functionality.

Doorknobs, keys, and hinges are all common hardware items made using metalwork.

Casting, forging, and welding are all processes used to shape metal in metalwork.

Riveting, soldering, and brazing are all techniques used to join two pieces of metal together in metalwork.

Casting involves pouring molten metal into a mold to create a desired shape.

Forging involves shaping metal by hammering it.

Welding involves joining two pieces of metal together using heat and a filler metal.

Soldering involves joining two pieces of metal together using a low-melting-point metal called solder.

Plating involves coating a metal surface with a thin layer of another metal.

Anodizing, galvanizing, and powder coating are all processes used to apply a protective coating to metal to prevent corrosion.

Laser cutting involves cutting metal using a high-powered laser.

Water jet cutting involves cutting metal using a high-pressure stream of water.

Plasma cutting involves cutting metal using a plasma arc.

CNC machining involves shaping metal using a computer-controlled machine.
