Aluminum bars are made of metal, of which aluminum is one of the most important materials. However, because aluminum is a metal with poor hardness, the bat can't be pure aluminum, and usually it is mainly alloy. Due to the rapid development of aluminum bar materials, aluminum bars with "aluminum", "copper" and "magnesium" alloys have become the general mainstream. The history of using aluminum bars began around 1970. Before that, baseball was almost dominated by sticks. The biggest advantage of aluminum bars is that they are extremely elastic and will not break at all. As long as you swing hard enough, you can usually hit the ball high and far. Therefore, for beginners, it is very easy to feel a sense of accomplishment with an aluminum rod swing. However, due to the current international baseball association's policy of actively promoting the use of wooden sticks in international competitions, the use of aluminum sticks has gradually decreased and almost disappeared in important international competitions; But at present, aluminum bars can still be seen in the third-level baseball game in China.
The compound bat is made of poplar, maple and bamboo chips. Some people call it "compression stick", "synthetic stick" and even "bamboo stick". Because the composite bat combines the advantages of wooden stick and aluminum stick, it has good elasticity, is not easy to break, and its swing strength will not be lost to aluminum stick, so it is usually not allowed to be used in general international official competitions; However, due to the policy that the International Baseball Association actively promotes the comprehensive use of wooden sticks in international competitions, composite sticks have always been regarded as transitional sticks before the comprehensive use of wooden sticks, and sometimes they can be used in domestic third-class baseball games. In the regional leagues of some university baseball teams in Japan, compound bats are also allowed.
The common materials for making wooden sticks are poplar and maple. Unlike compound bats, sticks must be cut from logs and cannot be compressed manually. In other words, the stick is a part of the original tree, so there are usually natural wood grains on the stick. The use history of wooden sticks is very long. It can be said that wooden sticks have existed since the invention of baseball. The biggest difference between wooden bars and aluminum bars is that they are poor in elasticity and easy to break. When you swing, you must fully grasp the hitting point in order to exert a strong swing force. Therefore, using a wooden stick to swing, we should pay attention to superb swing skills, not brute force; At present, under the policy that the International Baseball Association actively promotes the comprehensive use of wooden sticks in international competitions, the use of wooden sticks has become more common and is no longer the patent of professional baseball players. At present, wooden sticks have been gradually used in domestic third-class baseball games.
