Quality Inspection: Conduct conductivity and tensile tests per ASTM B209.
⚠️ Common Misconceptions
-
“Higher-strength alloys are always better.”
Reality: For pure conductivity, 1070’s lower strength is acceptable given its efficiency gains. -
“All aluminum plates conduct equally.”
Reality: Conductivity varies widely; 1070 leads the 1xxx series. -
“Pure aluminum corrodes too fast.”
Reality: 1070 exhibits high corrosion resistance in atmospheric and marine conditions.
