Beryllium Copper C173 / C17300


Level 4
Free-Machining Beryllium
Level 3
Used when Formation of Small Chips During Machining is Desirable
Level 2
Same Mechanical & Physical properties of Alloy 172

Farmer’s Copper Ltd. inventories C17300 beryllium copper round rod up to 1” diameter. C173 is known as Free-Machining Beryllium, and is used when the formation of small discontinuous chips during machining is desirable. Copper Alloy 173 beryllium has the same mechanical and physical properties of those of the unleaded Alloy 172.

Farmers Copper has ASTM B196 spec C173 in stock.

We can provide bar, saw cut to your specifications. Contact our sales staff to inquire on your requirements of C17300 Beryllium Copper.
