Easy-Form tubing is made from a copper-nickel alloy that is as strong as steel, but much easier to bend and flare. This alloy is approximately 90% copper and 10% nickel, and should not be confused with typical copper tubing found at hardware stores. The copper-nickel is much easier to form (so easy that it does not require a tubing bender - it can be bent and formed with just your hands). Ideal for use in brake lines and most other automotive hardline applications.
