Annealing is a heat treatment process that involves heating and slow cooling of metal at normal temperature.

• Annealing is used to improve the ductility, toughness, and machinability of metals.

• It involves heating the metal to a specific temperature and holding it there for a period of time.

• The metal is then slowly cooled down to room temperature.

• This process helps to relieve internal stresses and improve the metal's micr...read more

Sintering is a process of heating and compressing powdered metal to form a solid mass without melting it.

• Powdered metal is heated below its melting point to form a solid mass.

• The process is used to create complex shapes and improve the strength of metal parts.

• Sintering is commonly used in the production of automotive parts, cutting tools, and electronic components.
