Types of Materials for Making Locks
Locks are very common in our life, there are many types such as stainless padlocks and cam locks, metal cabinet locks, rope locks, etc., but do you know what materials locks are made of? The following are several common locks.
1.Stainless steel lock
The main purpose of locks is to ensure property safety, so the requirements for the durability of locks are getting higher and higher. Among all materials, stainless steel is the most durable material. The lock body of stainless steel locks is harder and firmer, and will not be easily damaged. Secondly, stainless steel locks can be Adapt to harsh climates and will not rust, so locks like stainless steel padlock and cam lock are choice for industrial chemical and outdoor use, but the price is relatively high.
2.Brass lock
Brass locks are the most widely used. Its corrosion resistance is second only to stainless steel locks. It also has the function of preventing rust and corrosion. On the other hand, brass locks are also widely used in households. The color and plasticity of brass are stronger. , It can be forged into locks of different shapes, so the locks made will be more beautiful and can be used in industry and daily life.
3.Zinc alloy lock
Compared with stainless steel and brass locks, zinc alloy is not rust-proof or strong. This material is easier to make locks with patterns, so most of the locks made of zinc alloy are used in house door locks, not suitable for industrial applications.
4.Steel lock
Steel is as strong and durable as stainless steel locks, and it is not easy to be damaged, but compared with stainless steel locks, it is easier to rust. It is not suitable for long-term outdoor use, but the cost is very low, so steel is mostly used to make accessories in the lock body.
5.Aluminum alloy lock
Aluminum alloy locks are used in aircraft or some aviation fields. Aluminum is lighter, so it will not be widely used.
Lock processing
However, no matter what material the lock is made of, it needs to be processed, especially the surface of the lock, and the lock body protection layer is added to the lock. In the industry, this part of the processing mainly strengthens the corrosion resistance of the lock, in addition to Carry out a series of component monitoring and lock body thickness, etc., each process affects the quality of the lock, so you must distinguish which lock is suitable for you.
Hey we have been turning in this part at a scrap metal plant now we.know the out side skin cover is a.very thin yellow brass but what we don’t know is what the two centers are made of they are calling it a aluminum alloy cast or power forged but it’s too heavy to be aluminum we.think it could be nickle the magnet don’t stick so can.
The dead bolt centers are way too heavy to be alum so what is it made of they say it is a zink alloy ok if so what is the other metal is it nickle number 3 hardness
