Bending Half Hard Copper Sheet

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.

Bending half hard copper sheet.

Deep drawing coining stretching and bending are common methods used to form components such as bathroom fixtures and other household products. We are going to review three bending scenarios with three different bending angles. Half hard brass is a nice balance between stiffness and workability. 060 soft h00 cold rolled h01 cold rolled high yield h02 half hard h03 three quarter hard and h04 hard.

Material bend radii and minimum bend size charts please note. Copper sheeting comes in thicknesses ranging from very thin copper foil to thick copper plate. Learn how to bend sheet metal so you. Copper nickels and other alloy families strength is increased in proportion to the amount of cold work.

Copper sheets plates are also noted for their high electrical and thermal conductivity and good corrosion resistance. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Below is a quick guide to help you determine which thickness best suits the needs of your project. The copper most commonly used for sheet and strip applications complies with astm b370.

Cartridge brass reflects the deep drawing characteristic of that alloy. Consider a sheet with a 20 mm thickness and a length of 300 mm as shown in figure 1. Types of copper and properties. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.

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. These forming operations include blanking piercing bending drawing and stretch forming spinning rubber pad forming and contour roll forming. It consists of 99 9 percent copper and is available in six tempers designated by astm b370 as. 60 90 and 120 and we will calculate k factor bend allowance and bend deduction for them.

Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one.
