Aluminum Alloys

 

The applications for aluminum alloys are almost limitless.  Choosing an Aluminum alloy for a particular application depends on many factors.  Our Sales Staff can help you with this decision.

Some considerations that should be taken into account are:      

1.        Foundry characteristics for the casting process that will be used;

2.        Required mechanical and other properties for the service intended;

3.        Mechanical properties over the service life;

4.        Corrosion resistance for the application;

5.        Machinability, pressure tightness and finishability, if necessary;

Another consideration that should be taken into account is the finished cost of the part.  The following among many other variables can directly affect the cost:

1.        The alloy chosen and the technical requirements of casting that alloy;

2.        Quantity of castings to be produced;

3.        Process used;

4.        Complexity of the shape of the part;

5.        The tooling used for producing the molds;

6.        Dimensional tolerances required;

7.        Inspection and quality standards required
