The Different Types of Bronze and Their Uses

Many people think that bronze is a naturally occurring metal, but it’s actually an alloy of copper and tin. As an alloy, one of the interesting properties of bronze is that you can mix it with other metals in various quantities to get different results. Here are some examples of bronze alloys that find a lot of use in the wider world:

  • Phosphor Bronze. Combining phosphorus with the normal mix of copper and tin results in lower electrical conductivity (it’s recorded at 15% of the normal conductivity levels). Combined with its durable nature, this makes phosphor bronze ideal for protecting electrical wiring from the elements and other outside forces.

  • Aluminum Bronze. If you want a harder mix, adding aluminum to normal bronze adds to its durability. Sheets of aluminum bronze are a popular purchase in the aircraft industry as the alloy is used in bearings, propellers, and fasteners for planes.

  • Manganese Bronze. The Navy finds manganese bronze very useful, as the manganese content makes it highly resistant to saltwater corrosion. This is why you can find them usually used in boat propellers.

  • Silicon Bronze. Silicon bronze is actually a mix of 3% silicon and 1% manganese. This makes it tough yet easy to mold into different shapes. Items made of this type of bronze, like door fittings and church doors, can withstand the elements better.
