G-10 CNC Machining

G-10 (also known as phenolic and epoxy-grade industrial laminate) is a high-pressure fiberglass laminate, a type of composite material with a low coefficient of thermal expansion. It is a flame resistant composite material used by many aerospace companies. It is also a strong material that does not absorb water which makes it an excellent insulator and really useful for electronics applications.

G10 and aluminum are comparable in strength and durability. G-10 is a little lighter and more resistant to temperature change. Aluminum is quite a bit more rigid and is more resistant to impact.

The difference between G10 and FR4 is that FR4 is a fire-retardant grade of G10 and it can be safely substituted when G10 is called out.

G10 is a fiberglass material that is most often used in the making of circuit boards. It is more stable and resistant to corrosion due to not being a metal. It is generally used in the medical, aerospace, and marine industries.

They are both phenolic laminates. However, Garolite is a brand name for G10, which is a fiberglass laminate. Other phenolics are made with paper, linen or other woven fabrics.
