Bending Half Hard Copper Sheet

Learn how to bend sheet metal so you.

Bending half hard copper sheet.

The copper most commonly used for sheet and strip applications complies with astm b370. The unit of measurement used to identify the thickness of a sheet of copper varies e g gauge mil ounces per square foot inches millimeters. Copper sheets plates are also noted for their high electrical and thermal conductivity and good corrosion resistance. 60 90 and 120 and we will calculate k factor bend allowance and bend deduction for them.

These forming operations include blanking piercing bending drawing and stretch forming spinning rubber pad forming and contour roll forming. 110 copper sheet plate is widely known for its architectural applications whereas the familiar green patina appearance is acheived when exposed to the elements copper sheets and plates have excellent hot or cold workability and is ductile when heated. Cartridge brass reflects the deep drawing characteristic of that alloy. Types of copper and properties.

We are going to review three bending scenarios with three different bending angles. Consider a sheet with a 20 mm thickness and a length of 300 mm as shown in figure 1. Material bend radii and minimum bend size charts please note. 060 soft h00 cold rolled h01 cold rolled high yield h02 half hard h03 three quarter hard and h04 hard.

Copper sheeting comes in thicknesses ranging from very thin copper foil to thick copper plate. Copper nickels and other alloy families strength is increased in proportion to the amount of cold work. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Deep drawing coining stretching and bending are common methods used to form components such as bathroom fixtures and other household products.

Copper nickel tubes are. Below is a quick guide to help you determine which thickness best suits the needs of your project. It consists of 99 9 percent copper and is available in six tempers designated by astm b370 as. This article reviews the general characteristics of copper and copper alloys and explains how these characteristics affect the behavior of strip in different types of forming operations.

The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius.
