im looking for a bat but i dont know what to get wood or aluminum what is harder wood or aluminum ?? what would be better for hitting hard balls with ( or maybe people ) haha no im joking i need help !!!!aluminum is, and hardness isnt everything.. theres bat speed, vibration differences after the swing, wider sweet spots, and durability. aluminum bats dominate wood bats in all these catergorieswhy dont get wack each one over your head and see which hurts more. than you\'ll get your answer, just kidding. you should know metal is always harder than wood. but for baseball, you want a wooden bat, better for the swing, and the grip. I used to play little league back in the day and used aluminum bats, and even with batting gloves my hands were always killing me after the game.Aluminum. When you hit the ball, it goes farther then a wooden bat. That is why MLB players can\'t use them, just in case of a line drive to the pitcher. They have enough problems dodging it, and this would get a lot more of them hit.Other related question
