Q1: What are the advantages of using the 6000 series of alloys in aluminum extrusions?

A: The 6000 series, which incorporates magnesium and silicon, provide good extrudability, 

strength, corrosion resistance, formability and machinability -- which explains why it’s also 

JJT’s alloy of choice for all our aluminum extrusions.

Q2: If I wish to send an electronic drawing to you, what types of files can you accept?

A: We accept many file formats such as DXF, DWG and IGES.

Q3: Why do extrusion companies always ask me to sign off on a drawing before they can

order tooling if I’ve already provided a drawing?

A: Oftentimes, we find a few key dimensions that are missing from the original drawing 

that need to be clearly identified. Other times, we have taken exception to a tolerance, 

dimension, alloy, note, surface condition, etc. It’s just our way of documenting exactly 

what we have agreed upon.

Q4: What is the difference between anodized and mill finished?

A: Mill is the raw state of aluminum as extruded - no surface treatment. Anodized (also

known as Satin Clear or Clear Anodized) is an electrolytic process. This process increases 

corrosion resistance and weather resistance.

Q5: What About Anodizer Rack Marks?

A: Electrical contact must be made to each part to be anodized. The more electrical 

current required, the greater the electrical contact. The size of the contact therefore 

depends on the anodizing process and the size of the part being anodized.
