Raw Material

The following list is not all inclusive, but does cover the majority of architectural hardware.

• Brass

  A mixture of copper and zinc. It is the most common base metal when it comes to high end architectural hardware that is easily manipulated and takes finishing well.

• Bronze

  A mixture of copper, zinc or tin (usually), and in most hardware cases silicone. White bronze will also include nickel. It is often used in ornate or rustic designed pieces as it casts very well.

• Stainless Steel

Steel with added chromium and nickel, which is used to diminish tarnishing and rust. It is an extremely durable material, with very limited finishing options.

• Aluminum

A strong, light weight metal used primarily for pocket door tracks and thresholds.

• Zinc/Pot Metal

Used only on the lowest tier cabinet hardware lines we carry this is typically a mix of recycled alloys, if not all zinc. It is not as durable as other alloys, does not hold a finish well, and is very low cost.

Uses

Pocket door track. Typically, aluminum.

Lock and latch assemblies typically consist of various base metal pieces the most common of which are brass, steel, and stainless steel. Cases and springs are steel. Most moving parts and tongues are brass. There is often a mix of plastic or nylon washers and fittings.

In cases of extreme exposure, mortise locks may be ordered with 100% stainless steel and plastic composition, at a premium.
