Metals.old – Micron Laser


With over 20 years of experience laser processing metals to the most stringent standards, you can be assured that the metals you purchase from Micron Laser will be of superior quality.   

Metal selection is generally based on the properties of strength, wear resistance or hardness, corrosion resistance, formability, and machinability. Surface finishes may be precision ground, unpolished, coated, polished, brushed, bright, or reflective.

If required, material certifications can be provided to document compliance to military (Mil-Spec), food and drug, automotive, and aerospace standards. This includes SAE recognized Ground Vehicle Standards; Aerospace Standards; and Aerospace Material Specifications (AMS). ASTM categories for metals include:

Steel Standards
Metallic Coating Standards
Copper Standards
Nonferrous Metal & Alloy Standards
Fatigue and Fracture Standards
Cast Iron Standards
Corrosion and Wear Standards
Corrosion and Wear Standards
Analytical Chemistry Standards


Lightweight, economical, corrosion resistant, easy to machine, and a good conductor of heat and electricity. CR = Corrosion-Resistant. Aluminum types include:

1100 – Ultra-CR
5086 – Marine Alloy
6101 – Highly CR
2024 – High-Strength
5205 – Color-Anodized
7050 – Very High-Strength
3003 – CR Formable
6013 – Strengthened Multipurpose
7075 – Hard High-Strength
5052 – Easy-to-Weld Highly CR
6061 – Multipurpose
5083 – Strengthened Highly CR
6063 – Highly CR Architectural



Offers good machinability at an economical cost but lacks corrosion resistance.

Carbon steel – an economical choice for machining and structural applications, and it can be surface hardened.
Alloy steel – greater strength and hardness than carbon steel, making it useful for high-stress applications. 
Tool steel – used to make cutting tools, and it can be heat treated for extreme hardness.

Stainless Steel - Click to shop

With at least 10% chromium, stainless steel types types 301, 302, 303, and 304 are excellent for corrosion resistance. The 300 series hardens by cold working, many in the 400 series can be hardened by heat treating, and those designated “PH” can be heat treated by the process of precipitation hardening. Stainless steel is generally formable and bendable, but types that harden by cold working can require more force to bend than carbon steel. Stainless steel can typically be more difficult to machine than steel. Stainless steel types include:

301 / 302 – High-Strength Multipurpose
321 – Weldable
440C – Ultra-Hard Wear-Resistant
303 – Easy-to-Machine
430 – Econ-Grade light-duty
440A – Impact and Wear-Resistant
304 – Multipurpose
416 – Very Easy-to-Machine
17-4PH – CR High-Strength
309 – High-Temp Multipurpose
410 – Wear-Resistant
A286 – Strengthened CR
316 – Super-CR
420V – Very Wear-Resistant
