Piping articles incorporating an alloy of copper, zinc, and silicon

A piping component comprising:

• a piping body with an open end;
• and
• a cold worked and not subsequently annealed alloy comprising (by weight percentage) 12% to 16.5% zinc, 0.265% to 1.8% silicon and sufficient copper so that the sum of the weight percentages of the zinc, silicon, and copper in the alloy is at least 99.7%,
• wherein, the alloy exhibits a thermal conductivity of about 45 W/m·K to about 70 W/m·K, and
• wherein, at least one of the following conditions is met:
• (a) the cold worked alloy was formed from a drawing of the alloy as-cast resulting in a diameter reduction within a range of 10% to 25%, and the cold worked alloy exhibits:
• (i) an ultimate tensile strength within a range of 340 MPa to 550 MPa, (ii) a yield strength within a range of 275 MPa to 480 MPa, and (iii) an elongation within a range of 20% to 30%,
• (b) the cold worked alloy was formed from a drawing of the alloy as-cast resulting in a diameter reduction within a range of 25% to 35%, and the cold worked alloy exhibits:
• (i) an ultimate tensile strength within a range of 550 MPa to 750 MPa, (ii) a yield strength within a range of 480 MPa to 655 MPa, and (iii) an elongation within a range of 12% to 20%, and
• (c) the cold worked alloy was formed from a drawing of the alloy as-cast resulting in a diameter reduction within a range of 35% to 45%, and the cold worked alloy exhibits:
• (i) an ultimate tensile strength within a range of 750 MPa to 900 MPa, (ii) a yield strength within a range of 655 MPa to 830 MPa, and (iii) an elongation within a range of 10% to 12%.
