ASTM B111 C68700 Aluminum Brass Tube
Standard Information: ASTM B111 is the American Standard "Standard for Copper and Copper Alloy Seamless Condenser Tubes." C68700 is a designation for aluminum brass within this standard, which specifies the technical requirements and performance indicators for this material.
Chemical Composition: Copper (Cu) content 76.0% - 79.0%, lead (Pb) content ≤ 0.70%, iron (Fe) content ≤ 0.06%, zinc (Zn) balance, aluminum (Al) content 1.8% - 2.5%, arsenic (As) content 0.02% - 0.10%.
Performance: Excellent cold working properties, high strength, and good corrosion resistance, suitable for processing into various shapes of pipe fittings.
Applications: Primarily used as fittings for condensers, evaporators, and heat exchangers, it is widely used in heat exchange equipment in the refrigeration, air conditioning, and chemical industries.
Overview: ASME SB111 is also a standard specification for copper alloys, but it is a separate standard from ASTM B111. Standards developed by the American Society of Mechanical Engineers (ASME) are highly authoritative and widely used in the engineering field.
Material Characteristics: ASME SB111 copper alloys offer high electrical conductivity and excellent thermal conductivity, as well as high strength and corrosion resistance.
Applications: Widely used in electronics, electrical appliances, automotive, aerospace, and other fields, as well as in engineering applications requiring high material performance.
In general, ASTM B111 C68700 mainly targets the application standards of specific brands of aluminum brass tubes in heat exchangers, condensers and other equipment, while ASME SB111 is a broader copper alloy standard system. The material properties and application areas involved are different from ASTM B111 C68700, but both play an important role in the manufacturing of heat exchangers and other related equipment.
