An improved Al&mdash;Si&mdash;Mg&mdash;Mn casting alloy that consists essentially of: about 6.0-9.0 wt. % silicon, about 0.2-0.8 wt. % magnesium, about 0.1-1.2 wt. % manganese, less than about 0.15 wt. % iron, less than about 0.3 wt. % titanium and less than about 0.04 wt. % strontium, the balance aluminum. Preferrably, this casting alloy is substantially copper-free, chromium-free and beryllium-free.

Al-Si-Mg-Mn casting alloy and method

A vehicle warning system consisting of a transceiver that augments the audible warnings of standard or emergency vehicles by transmitting and receiving a signal (in conjunction with activation of the typical audible warnings; e.g., horns and/or sirens) which, when received, triggers a visual stimulus to alert drivers to the hazardous condition within the vicinity of their vehicle.
