Delta Fastener Corp. can provide a wide variety of aluminum fasteners including; aluminum nuts, aluminum bolts, sockets, washers and more in aluminum fasteners. If we do not have your aluminum fasteners in stock (Inch or Metric) we can have these manufactured to your specification.

Material Notes:

Aluminum is a silver-colored, low density (2.7 g/cc) metal that finds use in a huge variety of commercial applications. Unalloyed aluminum is ductile, exhibits moderate strength, and is very resistant to corrosion under most circumstances. Aluminum can be dramatically strengthened by the addition of appropriate alloying elements (Cu, Mg, Mn, Si, etc.) and subsequent heat/work treatments. Aluminum is commonly used in both wrought and cast forms.

The low density of aluminum results in its extensive use in the aerospace industry, and in other transportation fields. Its resistance to corrosion leads to its use in food and chemical handling (cookware, pressure vessels, etc.) and to architectural uses.

Over 1250 Aluminum alloy entries are listed in MatWeb. Aluminum 1199 is the highest purity (99.99% Al min.) commercially available in structural form.
