Bending Half Hard Copper Sheet

Material bend radii and minimum bend size charts please note.

Bending half hard copper sheet.

The copper most commonly used for sheet and strip applications complies with astm b370. We are going to review three bending scenarios with three different bending angles. Types of copper and properties. Cartridge brass reflects the deep drawing characteristic of that alloy.

It consists of 99 9 percent copper and is available in six tempers designated by astm b370 as. Below is a quick guide to help you determine which thickness best suits the needs of your project. 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. 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 sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle. Half hard brass is a nice balance between stiffness and workability. Copper sheeting comes in thicknesses ranging from very thin copper foil to thick copper plate. Copper sheets plates are also noted for their high electrical and thermal conductivity and good corrosion resistance.

Deep drawing coining stretching and bending are common methods used to form components such as bathroom fixtures and other household products. Consider a sheet with a 20 mm thickness and a length of 300 mm as shown in figure 1. These forming operations include blanking piercing bending drawing and stretch forming spinning rubber pad forming and contour roll forming. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one.

Copper nickels and other alloy families strength is increased in proportion to the amount of cold work. 60 90 and 120 and we will calculate k factor bend allowance and bend deduction for them. 060 soft h00 cold rolled h01 cold rolled high yield h02 half hard h03 three quarter hard and h04 hard. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.
