Combination locks are commonly used to secure possessions and properties, including lockers, safes, and bicycles. These locks are designed to require a combination of numbers or letters to be entered correctly before the lock can be opened. While combination locks are often known for their convenience and ease of use, little attention is given to the materials used to make these locks. This article aims to shed light on the materials commonly used in combination locks.
Metal
One of the most common materials used in combination locks is metal, and more specifically, steel. Steel is known for its durability and strength, making it an ideal material for locks. The shackle, or the curved part of the lock that goes into the opening, is typically made of hardened steel. The body of the lock, which houses the locking mechanism, may also be made of steel or a combination of steel and other metals. Some locks also feature a zinc alloy construction, which is lighter but still sturdy.
Plastic
While metal is the most common material used for combination locks, plastic is also becoming increasingly popular. This is particularly true for combination locks used for lighter applications, such as lockers and luggage. The plastic used in combination locks is typically reinforced with other materials, such as steel wires, to ensure its durability and strength. These plastic locks are generally cheaper and lighter than their metal counterparts.
Aluminum
Another material used in combination locks is aluminum. Aluminum is known for its lightness, making it an ideal material for combination locks used on bicycles, backpacks, and other lightweight applications. Aluminum alloy combination locks are also available for added durability and strength. Aluminum combination locks are also resistant to rust, making them a great option for outdoor use.
Brass
Finally, brass is another material commonly used in combination locks. Brass is an alloy of copper and zinc, providing an elegant appearance and high resistance to corrosion. Combination locks made of brass come in various styles and are often used for padlocks and other security applications. However, brass combination locks tend to be more expensive than those made of other materials.
