Copper-nickel (also known as cupronickel) alloys are widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability. They have provided reliable service for decades while offering effective solutions to today’s technological challenges.

90-10 copper-nickel (C70600, CW352H), an alloy with 90% copper and 10% nickel, is the most commonly used alloy. It can be found in naval and commercial shipping, offshore oil and gas production as well as desalination and power generation. Alloys with 30% nickel content (C71500, C71640) and those which are more highly alloyed with aluminum, chromium or tin are used where greater resistance to seawater flow, sand abrasion, wear and galling, as well as higher mechanical properties, are required.

The addition of nickel to copper improves strength and corrosion resistance while allowing the alloy to remain ductile. Other elements can be added to copper-nickel to increase strength, corrosion resistance, hardening, weldability and castability.

Non-marine applications for copper-nickel include cryogenic applications, brake tubing and silver-colored coins, such as the 1- and 2-euro denominations and the 5-cent U.S. nickel. Since copper-nickel alloys have strong antimicrobial properties, they are marketed as hygienic "touch materials" to reduce cross-contamination and infections, particularly in hospital intensive care units.

These single flute countersinks produce ultra smooth, round countersunk holes in a wide variety of materials. The single cutting edge will cut faster than standard multi-flute countersinks and leave a finished hole every time. They can be used in hand drill and drill presses. They can be re-sharpened. Single cutting edge prevents chatter and produces smooth drilling action. This set includes four of the most popular sizes: .267, .298,.343 and .391. Shank sizes are 1/4 inch and will fit in any 1/4 or 3/8 inch. Cut angle is 82 degrees. Comes in wood store box.

Most standard square endmills have at least a .002 corner radius. This gives the cutting edge more strength as if it was perfectly sharp/square the edge would ...
