3 RESULTS AND DISCUSSION
3.1 BRINELL HARDNESS
The average Brinell hardness of as-cast components was
68 HBW. This value is bigger than the Brinell hardness
obtained by gravity die casting. The Brinell hardness
result for A356 T6 components was similar to A6061 T6
forging alloys [2] and nodular cast iron with a ferritic
matrix.
