There are many reasons why you should use ZAMAK alloys. Because of their benefits, ZAMAK alloys sometimes replace aluminum casting. This section mainly talks about the benefits of die-casting ZAMAK alloys.
Reason #1 High-Fluidity
Fluidity refers to how easily molten metal flows into molds during casting. High fluidity means that the ZAMAC alloy can easily do this job. Because of this feature, you can create even more complex designs. The molten metal can reach every corner of the design for high fluidity. As a result, you can get better finished parts.
Reason #2 Tough & High Rigidity
Die-casting ZAMAK alloys are tough and can resist deformation. Because of this, these alloys are durable and perform well in continuous operation. ZAMAK 2 and 5 offer high rigidity and toughness.
Reason #3 High Strength-To-Weight Ratio
Die-casting ZAMAK alloys are strong yet lightweight. Aluminum offers a stronger strength-to-weight ratio than ZAMAK. Note that aluminum’s tensile strength is 310MPa, while ZAMAK’s is 280MPa. However, ZAMAK die-casting parts are also prevalent in many uses.
Reason #4 Low Melting Point
The melting point of die-casting ZAMAK alloys ranges from 380 to 420 degrees Celsius (Except for ZAMAK 2). It means you can quickly melt and solidify.
There are some benefits of a low melting point. (1) It reduces the energy cost. (2) It makes the production faster. (3) It also simplifies the production. (4) It ensures fewer defects on casting metal parts.
Reason #5 Excellent Adhesion
Excellent adhesion means that ZAMAK die-casting alloys effectively bond with coatings. You can do a wide range of surface treatments. Because of this, your final part can get a good appearance. You can give it a premium look as per your design. Besides, it also gives your metal part good corrosion resistance.
Reason #6 Excellent Wearing And Bearing Properties
Die-casting ZAMAK alloys resist wear and effectively endure friction. ZAMAK parts typically maintain quality and functionality. They remain intact even under continuous stress.
This feature is critical in die-casting. It reduces replacement costs, which is crucial for moving parts like gears and levers.
Reason #7 100% Recyclable & Environmentally Friendly
ZAMAK die-casting alloys are 100% recyclable. You can completely melt and reuse it. It won’t waste any material, and you can use all scrap.
This feature typically reduces raw material costs and ensures no environmental impact. Note that recycled ZAMAK alloys retain the same quality as new material.
Reason #8 Cost-Effective
ZAMAK die-casting alloys are cost-effective solutions. They usually cost less than aluminum. According to 2024 market trends, ZAMAK metals are slightly more expensive than aluminum. However, ZAMAK alloys are cheaper than other metals and their alloys.
