PROTOTYPE PRODUCT INFO

Zinc-Aluminum Con-Cast Bar Stock

Zincaloy continuously-cast bar stock features uniform, porosity-free composition and structure. These qualities provide excellent comparison for the end-user to evaluate their final product suitability for the appropriate application. In other words, the con-cast zinc alloy products have similar mechanical properties of pressure die castings. In addition, the con-cast bars can be used to produce moderate quantities of finished zinc alloy parts.

Zincaloy offers a reliable resource of con-cast solid round, square and rectangular bar sizes made with commercial zinc alloys.

Commercial Zinc Alloys

Advantages of continuous-cast bars made of commercial zinc alloys include:

  • Providing the end-user with reliable assessment of the die-cast part design before making commitment to production.

  • Prototyping which eliminates costly retooling of the production die assembly and minimizes time lost if the parts fail. 

  • Scenarios where the production part fails due to defects or design, machined con-cast parts having similar die-cast properties can resolve a production crisis.

  • Circumstances where the supply of die-cast parts are delayed, the machining of con-cast bars can provide a temporary solution.

  • Producing low to moderate quantities of parts for sales and marketing purposes.

  • Reference industry standards include: ASTM B86, SAE and UNS.

Why Prototype Prior to Die-Casting?

Zincaloy supplies high quality con-cast zinc alloy bar stock for prototyping. Prototyping is a very important stage in product development, by helping engineers quickly determine whether the zinc alloy parts can perform to the product design criteria.

 

There are many different methods to prototype for zinc die castings.  Machining prototype parts from con-cast zinc bar stock is a fast and simple approach, having similar properties as zinc die castings. Other advantages of using con-cast bar stock are:  

  • The material is readily available for reduced lead times.

  • There is no mold or tooling required.

  • Con-cast bar stock can be used for  functional testing as well as appearance requirements such as shape, fit, and surface finish.

Zinc Alloy Properties

The following table gives the properties of Con-Cast bars compared to Die Castings.  As shown, the Con-cast bar properties are similar to a die cast component, with the exception of the elongation.  If the elongation is required, then a simple heat treatment of alloy ZA-12 will produce similar ductile results as Zamak 3 die castings.  Heat treated ZA-12 bars are available upon request.

Shapes & Sizes

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 thickness starting at 5/8". In addition, hexagonal bars and custom shapes are available upon request.
