Frequently Asked Questions
Common materials include aluminum alloys for lightweight applications, cast iron for superior strength, and various steel alloys or sandwich composites depending on the specific engineering requirements.
We use three primary methods: Brinell hardness for general castings (≤ HB450), Rockwell hardness (HRA for high hardness, HRC for quenched steel), and Vickers hardness for thin plates and surface-hardened layers.
Yes, we specialize in OEM services where the material, casting process, and design are customized to meet the specific project specifications of the client.
HRA is typically used for extremely hard materials like cemented carbides (usually > 70 HRA), while HRC is the standard for hardened steel parts, ranging from 20 to 67 HRC.
They serve as the reservoir for engine oil, protecting the internal lubrication system from debris and providing a secure seal for the bottom of the engine block.
The hardness value is a critical indicator of the material's wear resistance and processing quality, directly impacting the longevity and reliability of the component in industrial use.
