If you want to see if your college baseball bats are made from one of these advanced alloys, simply look at the bat. Usually, manufacturers are so proud of the fact that they ll announce it in big bold letters on the bat. Then again, if you re bat is -11 or lighter, it is required by law not to state what kind of alloy is used in its fabrication. In any case, these lighter bats probably do not contain the stronger newer alloys. To make weight, the manufacturer probably used a lighter alloy for the thinner walls of the bat.
If you want to be able to know exactly what is in your college baseball bats, look for the grade number on them. For instance, a grade number of 7046 means that the bat is fabricated with standard aircraft aluminum, a material fit for many budget bats.
The grade 7050 means the aluminum alloy contains an amount of copper, which makes it one-third stronger than 7046. Other numbers and grades, of course, designate other alloy blends and different strengths.
