High-strength aluminum sand casting alloys such as type 201 and 224 offer yield strengths upwards of 55,000 psi on bars cut from castings. The range of properties represented expands the technical base and design strength range of aluminum castings their utilization will result in longer service life as a consequence of improved heat rejection capability and lowered running temperatures under high ambient temperature operation. Significant weight savings realized in individual applications should enhance vehicle mobility characteristics.
