Conversion. Copper and brass processing. Intermediate rolling operation on strip. Strip brass and copper, cast as thick heavy cakes, is reduced by successive rolling to lighter gauge sheet, strip, bar, plate, wire or foil. 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. Stocks of partially completed lengths of seamless copper tube in many sizes. These have still to go through several more draws through dies on drawbenches. Each draw reduces them in diameter and wall thickness, and lengthens them out. Then, before the tubes leaves the mill, the ends will be sawed off straight and clean.

Conversion. Copper and brass processing. When "slabs" (brass or copper castings in the form of long flat cakes) are cast, the upper end of the casting, the last part poured, is apt to be slightly blown and drossy. This end is cut off by large shears before the casting is sent to the mill to be fabricated into sheet metal. Chase Copper and Brass Company, Euclid, Ohio

Conversion. Copper and brass processing. Analyzing the amount of copper and lead in the brasses. In this test the laboratory checks samples of brass from the mill's production to make sure they are the correct mixture. Samples are dissolved in acid and subsequently electrolyzed. The copper is plated out on the cathode negative electrode and the lead on the anode positive electrode. The percentages of each metal present are determined by weighing the electrodes before and after electrolyzing. Chase and Brass Company, Euclid, Ohio

Conversion. Copper and brass processing. Pickling lengths of copper water tube in a brass and copper mill. After annealing, or softening by heat to reduce brittleness and allow further drawing, tubes are "pickled" in a sulphuric acid solution to remove oxide and scale that result from the anneal. Bundles of the tubes are picked up by electric cranes and transported from the pickle to a rinse bath of water. The tubes are then returned to the drawbench for re-drawing down to smaller diameters.

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. Gaging drawn brass bar. Brass or copper supplied in bars finds many uses in the Navy. Most frequently it is cut to short lengths and machined to form parts of machinery, guns, and other implements of war. While dimensions are apt to vary, even slightly, close tolerances as to width and thickness must be observed. Here an inspector is checking dimensions with a micrometer.

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

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.
