Aluminum Welding Services

Aluminum is a lightweight and strong material making it an excellent choice for the aerospace and airplane manufacturing industries. Superior Joining Technologies, Inc. builds custom CNC aluminum parts while also offering aluminum welding services for these industries and many more. We have the expertise, experience, and equipment needed to complete detailed projects quickly.

Aluminum is known for its high machinability, good strength-to-weight ratio, and natural corrosion resistance. Aluminum also provides excellent affordability. As pure aluminum is soft and has limited strength, small amounts of copper, magnesium, and zinc are often included in aluminum to increase strength.

Properties and Benefits of Aluminum

• Easily machined
• Ductile
• Good strength-to-weight ratio
• High thermal and electrical conductivity
• Low density
• Lightweight
• Non-magnetic
• Excellent corrosion resistance
• Excellent chemical resistance
• Reflects heat and light
• Recyclable

CNC Aluminum Machining

Superior Joining offers the manufacturing of custom CNC aluminum parts with precise tolerances while meeting your deadline and order quantities. Aluminum components are offered in various sizes and shapes, from the simplest to the most complicated.

Aluminum CNC machining reduces manufacturing costs, improves production speed, and increases efficiency. We provide tolerances as close as +/- .0002” and have the state-of-the-art machine tools, tooling, and software needed for the high-quality aluminum product you need.

Aluminum GTAW Welding Services

Aluminum parts are welded with incredible difficulty and require a level of skill and experience offered at few places. At Superior Joining, we use TIG (tungsten inert gas) welding to provide quality parts for our customers. We have weld procedures that deliver the correct mix of heat input and speed as well as experienced and consistent welders to successfully overcome common aluminum limitations such as porosity.
