Uncle Sam test brass alloys. Washington D.C. To determine the correct amount of alloys necessary for desired results in the making of castings and other uses, the U.S. Bureau of Standards is conducting daily tests. 600 different portions of the alloy are used at the present time. The tests are made with brass bars which are melted in a high frequency induction furnace and the temperatures are recorded before and during the pouring into the molds.

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.

Conversion. Copper and brass processing. In the brass and copper casting shop, the operator of an electric furnace is pouring the molten metal into molds to form shells, or rough tubes, which are later formed into finished tubes. Tubes are formed by casting molten metal into these molds in which a refractory core has been inserted. The molds are mounted on a turntable, which brings them into position to receive the pouring.

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. 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. Casting a billet from an electric furnace. Modern electric furnaces have helped considerably in speeding the production of brass and other copper alloys for national defense. Here the molten metal is poured or cast from the tilted furnace into a cylindrical mold to form a billet. The billet later is worked into rods, tubes, wires or special shapes for a variety of defense uses. Chase Brass and Copper Company, Euclid, Ohio
