Many die casting companies prefer to use zinc for die casting because of the number of advantages this component offers. Die casters also use aluminum alloys for shaping metal parts into desired shapes but several expert Mexican die casters claim that working with zinc alloys is far more easier and efficient than working with die cast aluminum alloys.
Some of the unique characteristics of zinc alloys that make them a perfect component for die casting purposes are as follows.
- High electrical conductivity
- Greater strength
- Excellent thermal conductivity
- Low cost raw materials
- High dimensional stability and accuracy
- Greater ability to cold form
- Fully recyclable
- High resistance to corrosion
- High quality finishing characteristics
The greater strength and hardness of zinc alloys make them an ideal choice for a number of solution and they are also an excellent alternative to pressed, machined, fabricated, and stamped components. Complex net-shaped zinc housings that come with precisely designed thin walls provide offers incredible shielding properties and electrical performance.
In addition to that, the cast-ability, structural integrity, and wear resistance of zinc alloys make them a perfect choice for creating multi faceted highly complex shaped finished products with ease. These types of products are commonly used in electronics and automotive safety industries.
Some of the commonly used zinc alloys in die casting process are listed below.
ZAMAK 2
ZAMAK 2 is also commonly known as Kirksite or Zinc Alloy 2 among die casters. This zinc alloy possesses incredible die casting characteristics such as a superior creep performance than most Zamak alloys, as well as an excellent vibration attenuation and damping capacity when compared aluminum die cast alloys. In addition to that, ZAMAK 2 is also highly durable and has incredible hardness and strength levels.
ZAMAK 3
ZAMAK 3 is one of the most widely used zinc alloys in several die casting companies and it is always the primary choice of Mexican die casters when they are die casting zinc. This alloy possess an excellent balance of desirable mechanical and physical properties and it has a long term dimensional stability.
ZAMAK 5
Zinc Alloy 5 or ZAMAK 5 is famous among die casters because of its larger copper content then ZAMAK 3. The larger copper content makes the zinc alloy a lot more stronger and durable. Additionally, ZAMAK 5 is also more readily finished, plated, and machined than most zinc alloys.
