Frequently Asked Questions (FAQs)

1. What is aluminum bar used for?

Aluminum bars have various uses across different industries. They are commonly used in manufacturing machine and equipment parts, as well as in architecture and engineering for structural components, frames, and other key parts. Aluminum bars can also be found in medical assemblies, aircraft, firearms, and semiconductor manufacturing equipment.

2. Is aluminum flat bar strong?

Yes, aluminum flat bars are known for their strength. They have a high resistance to corrosion and an excellent weight-to-strength ratio. The T6511 temper, which means it has been heat treated, provides additional strength with a yield strength of 35,000 psi. The 6061 aluminum used for flat bars meets ASTM B221 specifications.

3. What are the different types of aluminum bars?

There are various types of aluminum bars available. Some common shapes include round bars, rectangle bars, manifold bars, hex bars, and even tubing and pipe. These different shapes allow for versatility in applications and can be selected based on specific project requirements.

4. Why can't you put aluminum on steel?

Aluminum and steel should not be put in direct contact with each other because it can cause corrosion. When these dissimilar metals come into contact in the presence of a corrosive electrolyte, such as moisture, corrosion can occur. This is particularly true when aluminum is in contact with stainless steel.

5. Why use aluminum over steel?

One advantage of using aluminum over steel is its natural non-corrosive properties. Aluminum forms an oxide film that naturally protects the metal from corrosion. Unlike steel, aluminum reacts with oxygen to create this protective oxide layer. This makes aluminum a preferred choice in applications where corrosion resistance is important.

6. What is stronger: titanium or aluminum?

Titanium is stronger than aluminum. Titanium has a higher tensile strength, ranging from 230 MPa to 1400 MPa, compared to aluminum's range of 90 MPa to 690 MPa. Pure titanium is stronger than pure aluminum, although the strength can vary depending on alloy composition and other factors.
