Material Selection Guide

If you are new to laser cut sheet metal, CNC cut composites, and fabrication, we’ve created this guide to help you select the right material for your project.

Please keep in mind that this list is not all-inclusive, but it should help point you in the right direction. Our team of Application Engineers is always available to help answer questions too, email us anytime - support@sendcutsend.com


Placement: Outdoors

Material Recommended Comments
Aluminum Aluminum will do well outside, but will turn a dull grey and oxidize over time
Brass   Not recommended outdoors unless coated or polished. Will patina and tarnish easily.
Copper   Copper is great for decorative outdoor use if you prefer a green patina
Cor-Ten Steel Cor-Ten is a special alloy designed to last virtually forever outside. It develops a rusty patina that protects it indefinitely.
Mild Steel   Mild steel will rust quickly if left uncoated.
Stainless Steel Our preferred material for outdoor applications when no coating will be applied
Carbon Fiber   Not recommend for long term outdoor use since UV rays can damage the composite
ACM Excellent for signage
Titanium Very stable, will not corrode or patina.

Usage: Signage or Decoration

Material Recommended Comments
Aluminum   Aluminum is relatively soft and flexible, and will turn a dull grey if left uncoated.
Brass Brass is great for decorative use. We recommend adding a clear coat or polish to prevent patina. 
Copper Copper is great for decorative use. We recommend adding a clear coat or polish to prevent patina.
Cor-Ten Steel Cor-Ten is a special alloy designed to last virtually forever outside. It develops a rusty patina that protects it indefinitely.
Mild Steel   Mild steel will rust quickly if left uncoated.
Stainless Steel Our preferred material for signage and decorative items that will not be painted or coated.
Carbon Fiber   Cost-prohibitive for decorative uses.
ACM Excellent for signage.
Titanium   Cost-prohibitive for decorative uses.

Usage: High Strength

Material Recommended Comments
Aluminum (6061, 7075) 6061 and 7075 series Aluminum is much stronger and stiffer than our standard 5052 series. 7075 Aluminum is comparable to titanium for strength.
Brass   Brass is great for decorative use, but is very soft and ductile. Not recommended for any application subject to load or bending forces.
Copper   Copper is great for decorative use, but is very soft and ductile. Not recommended for any application subject to load or bending forces.
Cor-Ten Steel   Similar in strength to standard mild steel (A36).
Mild Steel (4130, AR500) Our 4130 series and AR500 steel are very high strength and offer significant advantages over standard mild steel (A36).
Stainless Steel Significantly stronger than mild steel, with increased weight. Will not corrode or rust.
Carbon Fiber Our highest strength-to-weight material. Incredibly strong and rigid. Not recommended for use in temperatures over 140 degrees F.
ACM   Not recommended for high-strength or load-bearing applications.
Titanium One of our highest strength-to-weight materials. Incredibly strong and rigid.
