Selecting the appropriate aluminum alloy for your particular casting can be difficult to say the least. Some alloys appear to be perfect in every way except they are difficult to pour for the foundry, which makes their laboratory properties virtually unobtainable. We can recommend the material that will work best for your casting and still be economical to produce.
Use the chart below to assist you in your selection of the right aluminum alloy or call us for some input. We are ready to help in any way.
