Hardening of metals is a process used to increase the hardness, strength and durability of a metal. This process is usually used for copper, zinc, silver and other metals.
Hardening of metals is usually carried out in a special hardening furnace that is capable of reaching very high temperatures. The process involves several steps, including heating the metal, cooling and then defatting.
In the first step, the metal is heated to the temperature required to form a crystalline structure. The metal is then quickly cooled to room temperature.
In the next step, the metal is cooled with a rapid air or water jet. This process is called de-hardening and causes the crystalline structure of the metal to become stronger and its strength to increase. Finally, the metal is treated with oil or other lubricant to prevent corrosion and wear.
Hardening of metals is generally considered an effective way to increase the durability of metal. This process is often used to produce high-end products, including tools, furniture, cookware and even aircraft parts and other components that our company manufactures for customers.
