Productomschrijving
Product Overview ASTM B111 UNS C68700 aluminum brass tube , also designated CuZn20Al2 (CuZn20Al2As in EN 12451 / JIS H3300 C6870 / BS 2871 CN110 nomenclature), is a seamless copper–zinc–aluminum alloy heat exchanger tube engineered for continuous duty in aggressive cooling-water service. Its nominal chemistry of approximately 76–79% copper, 1.8–2.5% aluminum and a controlled arsenic addition of 0.02–0.06% to inhibit dezincification allows the alloy to develop a thin, self
