1. 브리넬 경도 시험 방법: 이것은 일반적으로 사용되는 금속 경도 시험 방법입니다., 다양한 금속 및 합금에 적용 가능. 이 방법은 표준 기하학적 모양과 크기의 강철 공 또는 드릴 비트를 사용합니다., 테스트할 알루미늄 판에 특정 하중을 가합니다., 압입 깊이에 따라 경도 값을 결정합니다.. The hardness value of aluminum plate is usually expressed in Brinell hardness (HB).
2. Wright hardness test method: This is also a commonly used metal hardness test method, especially suitable for thinner metal sheets. This method uses a drill bit with a standard geometry and size to apply a load on the aluminum plate to be tested at a certain rate, and then calculates the hardness value based on the penetration depth of the drill bit into the aluminum plate. The hardness value of aluminum plate is usually expressed in Wright hardness (HR).

No matter which test method is used, it needs to be tested under suitable conditions, such as under constant temperature, humidity and load conditions, to ensure the accuracy and comparability of test results. 동시에, before the hardness test, the aluminum plate needs to be surface treated and flattened to ensure that the test results reflect the hardness of the aluminum plate itself.
