These smaller ingots are intended to replace extruded stock and could be forged or impact-extruded without scalping. This same alloy has consistently achieved an ultimate in excess of 90,000 PSI in the T6511 extruded condition. Initiated a Quality Assurance Program to achieve ISO 9000 by 1994. First production orders of 4032-type alloy for forged pistons approved and 2618 alloy to be tested for racing pistons. Research and development work also begun on CNG cylinders.
New alloy tests satisfactory in cylinder burst and fatigue tests.
Also tested as a replacement for 7129 air bag canister. Research project started to develop ingot suitable for semi-solid forming. Dendritic to globular structure change achieved at high temperatures by semi-solid thermal transformation. 1994 Patent for new alloy filed in April and registered with the Aluminum Association in June as AA6069. New tests included disc part for General Motors' automatic overdrive transmission.
