Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 edition. Excerpt: ... diameter of a test-piece, in tension, along the stretched portion is seen in the following record of test of copper fluxed with fluor-spar, a flux which was expected to give much better results than were in this case actually obtained. TABLE XXXVII. TEST OF CAST COPPER (FLUXED WITH FLUOR-SPAR), No. 51 B.--Material: Copper, cast in hot iron mould, fluxed with fluor-spar.--Dimensions: Length, 6.19" (15.5 cm.); diameter, 0.798" (2 cm.). Diameter of fractured section, 0.763 inch. Tenacity per square inch, original section, 20,440 pounds (1,437 kilogs. per sq. cm.). Tenacity per square inch, fractured section, 22.353 pounds (1571 kilogs, per sq. cm.). The following measurements were made of the diameter of the piece after breaking: Inch. At fractured section o. 763 % inch from fractured section 0.765 1 inch from fractured section "7!r 2 inches from fractured section 0.766 3 inches from fractured section "76f 4 inches from fractured section 0.766 inches from fractured section '7?7 5 inches from fractured section 0.768 6 inches trom iractured section 0.768 6inches from fractured section 0.774 The importance of effective fluxing and of skill and care in melting and casting copper, are well shown by a comparison of the figures given above for ingot copper with those obtained for the several re-cast samples, and even better by contrasting the figures obtained for the latter with those to be given for rolled and drawn copper, which may be taken to represent the most perfect attainable soundness. Rolled Copper as tested by the Author, in bars purchased in the market, had a tenacity of 32,000 pounds per square inch and reduced in section 40 per cent. Two samples from the same bar gave the same figure. Rolled copper has been tested by a...show more
