Eastern Alloys is now offering Con-Cast Zinc Bar Stock for prototyping. Prototyping is a very important stage in product development, by helping engineers determine if parts can or cannot be made in the material being tested.
There are many reasons to prototype including:
There are many different ways to prototype for zinc die castings. Machining prototype parts from Con-Cast Zinc Bar Stock is a fast, simple and easy approach, producing very similar properties as actual zinc die castings. Other advantages of using Con-cast Zinc Bar stock are:
The following table gives the properties of Con-Cast parts compared to Die Casting and Sand Casting processes. As shown, the Con-cast zinc bar stock properties are very similar to the die casting component, with the exception of elongation. If elongation is a required property, than a simple heat treatment of ZA12 alloy, will produce very similar results to Zamak 3 die castings. Heat treated ZA12 bars can also be available upon request.
Ultimate Tensile Strength
(%) in 2" bar
|Zamak 3 (Con-cast)||45.6||38.1||1.6||101|
|Zamak 3 (Die Cast)||41.0||32||10||82|
|ZA12 (HT) (Con-cast)||45.5||35.6||11||93|
|ZA12 (Die Cast)||58.5||46.5||5.5||100|
There are many sizes and shapes of con-cast bar stock available, including round bar stock diameters ranging from ¾" to 9" and rectangular bar stock sections of 5/8" to 8". Hexagonal bar stock is also available upon request.
