Aerospace Manufacturing

Metals for aerospace manufacturing, namely stainless and aluminum for aerospace metal-to-metal bonding, are vital to the industry. The uses of these metals across the aerospace industry often require exceptional performance, strength or heat resistance, even at the cost of considerable expense in their production or machining. Others are chosen for their long-term reliability in this incredibly safety-conscious field, particularly for their resistance to material fatigue.

stainless and aluminum for aerospace metal-to-metal bonding

The engineering necessary materials and specifically the use of stainless and aluminum for aerospace metal-to-metal bonding is incredibly important within aerospace engineering and have considerable oversight and standards. 

There are a few key metals and metal alloys used in the aerospace industry:

Aluminum

Although incredibly lightweight, commercially pure aluminum has a tensile strength of about 13,000 psi. Cold working the metal can approximately double its strength. Aluminum is commonly alloyed with other elements such as manganese, silicon, copper, magnesium, or zinc to further increase strength

Another major benefit of aerospace usage is that at subzero temperatures, aluminum is stronger than at room temperature and is no less ductile. Boasting a high strength-to-weight ratio and good formability, aluminum also has a beneficial anti-corrosion mechanism. When exposed to air, aluminum forms a hard, microscopic oxide coating which seals the metal from the environment

Stainless Steel

For many years, Aluminum was the primary material used for manufacturing aerospace components due to it’s incredibly high tensile strength as well as being lightweight. Stainless steel, however, in specific alloys, can offer higher tensile strength than aluminum, though generally with a heavier weight. 

Stainless steels are used in aerospace applications because they are resistant to corrosion and high-temperature oxidation and maintain their mechanical properties over a wide temperature range. It’s generally used for engine and exhaust components, landing gear, and key joints in an aircraft’s superstructure.

Testimonials

“I have worked with Polished Metals periodically throughout my 18 year carrier in the custom metal fabrication industry. They have been a consistent, reliable vendor for me both in regards to informational needs and as a product supplier. Quotes are often required to be turned around by me very quickly and Bob Gunther at Polished Metals sends me pricing and lead-times extremely fast. Our product arrives when we are told it will and if there are any delays (which does not happen often) we are informed ahead of time, which is appreciated. Product arrives undamaged and is of good quality 99% of the time and when there is an issue with damage or defects Polished Metals responds quickly and makes things right quickly. I highly suggest using Polished Metals for your quality metal needs.”

“Our company produces and installs complex high-end projects in New York City. Procuring the materials for projects like the Edge Observation Deck at Hudson Yards can be extremely involved. Polished Metals exceeded our requirements for all our architectural metal needs on this and many other demanding NYC projects. Over the years they have provided everything from raw material to complex fabricated components for our installations. The key to our relationship has been outstanding communication and trust. As anyone in the construction industry knows things can change in an instant, how a company responds to those changes is critical. Mary and the whole team at Polished Metals have shown that they not only respond but have come through for us time and again.”

“Polished Metals has been a Preferred Vendor of ours for over a decade. Our corporate philosophy dictates that we have Alternate or Secondary Supplier for all product, with the exception of #8 Mirror Polished Stainless Steel. We’ve tried to qualify other suppliers to no avail, as none of them can compete in any of the critical categories. The Customer Support provided by Bob Gunther cannot be replicated, pricing is fair, delivery is always on-time and quality is fantastic. As the Corporate Purchasing Manager for the last 7 years, not once have I had a negative experience with Polished Metals. I can’t say enough good things about them.”
