Conversion. Copper and brass processing. Here is a stock of billets, or solid cylindrical brass or copper castings, which have been sawed to length. These billets will be heated and put through a powerful extrusion machine, which will extrude rods, tubes or other special shapes from them. Billets are cast six inches to eight inches in diameter and usually from four to ten feet long. These are sawed to shorter lengths before they go to the extrusion machines.

Conversion. Copper and brass processing. Drawing seamless copper tube. Rough cast tubes tapered at one end to fit through a die are gripped in the tongs of the electric motor-driven vehicle on the drawbench and pulled or "drawn" through the die to be reduced to the desired size. Tubes usually are redrawn many times; each successive "draw" reduces the diameter, and increases the length. Brass tubes need to be annealed or softened between each draw, but copper tubes can be drawn several times without intermediate annealing. The tapered nose of the tubes may be seen just behind the drawbench operator. Chase Copper and Brass Company, Euclid, Ohio

Conversion. Copper and brass processing. Many parts and products used by the Army and the Navy must stand up under severe service conditions. Here the strength of a specimen of brass is being determined. The results of these tests enables engineers to select metals that have the strength and stiffness needed for various machined parts for guns and equipment. This testing machine records the tensile of yield strength of a metal specimen--its resistance to being pulled apart. A specimen in the machine is pulled until it breaks, and the load necessary to break is recorded. A meter attached to the specimen measures the amount of stretching.

Here's one of the intermediate rolls used in the production of strip. The man is coiling the strip as it comes from the rolls. Chase Copper and Brass Company, Euclid, Ohio

Conversion. Copper and brass processing. The inside of a large brass and copper tube mill. Copper tubes are made in many sizes, and in many alloys, and are needed for war production in hundreds of different ways--from small diameter tubing for gas and oil lines in airplanes and tanks and motor cars to large diameter tubes used in construction of our battleships. A tube annealing furnace may be seen to the right. Chase Brass and Copper Company, Euclid, Ohio

Conversion. Copper and brass processing. This sample of brass strip is being tested on a Rockwell Hardness Testing Machine. This test is based upon the depth a steel ball penetrates the metal. A minor load is applied first to hold the ball in position, and then a major load is applied. The dial on the machine measures the depth of the penetration. This test is made to check the physical properties of the metal. Chase Copper and Brass Company, Euclid, Ohio

Conversion. Copper and brass processing. Copper tube is made either by extrusion or piercing. In the piercing method, illustrated here, a hot round billet, or solid piece of copper, about fourty-five inches long, is rotated between tapered rolls and forced against a pointed mandrel which pierces the center of the billet. The billet then emerges in the form of a tube about eleven feet long. The Chase Copper and Brass Company, Euclid, Ohio

Conversion. Copper and brass processing. Drawing seamless copper tube. Rough cast tubes tapered at one end to fit through a die are gripped in the tongs of the electric motor-driven vehicle on the drawbench and pulled or "drawn" through the die to reduce them to the desired size. Tubes usually are redrawn many times; each successive "draw" reduces the diameter, and increases the length. Brass tubes need to be annealed or softened between each draw, but copper tubes can be drawn several times without intermediate annealing. The tapered nose of the tubes may be seen just behind the drawbench operator. The tube is checked with a micrometer after being drawn, to make sure it is the right diameter. The man looking through the short section of tube is inspecting the inner surface for flaws. The Chase Copper and Brass Company, Euclid, Ohio
