Aluminium-conductor steel-reinforced cable coating thickness would be designated GC2. Higher strength grades of steel are designated high-strength (3), extra-high-strength (4), and ultra-high-strength (5). An ultra-high-strength galvanized steel core with class A coating thickness would be designated GA5. The use of higher strength steel cores increases the tensile strength of the conductor allowing for higher tensions which results in lower sag. Zinc-5% aluminium mischmetal coatings are designated with an "M". These coatings provide increased corrosion protection and heat resistance compared to zinc alone. Regular strength Class "A" mischmetal thickness weight coated regular strength steel would be designated MA2. Aluminium-clad steel is designated as "AW".
What It Is! (Kahil El'Zabar album) What It Is! (Kahil El'Zabar album) What It Is! is an album by American jazz percussionist Kahil El'Zabar, which was recorded in 2012 and released on Delmark.
