G10 CNC Machining

Garolite G-10 (also known as phenolic and epoxy-grade industrial laminate) is a composite material with a low coefficient of thermal expansion.

G10 CNC machined parts are known for their excellent electrical insulating properties, mechanical strength, and dimensional stability.

Additionally, it does not absorb water and is an excellent insulator, which makes it useful for electronics applications.

FAQs

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.
