7000 series high-strength aluminum alloy ARK600 ultra-high-strength hex bolt
ARK600 Super Strong Hex Bolt
By adopting high-strength aluminum alloys and implementing advanced forming techniques with special heat treatment, we have achieved "tensile strength of 600 N/mm² and yield strength of 500 N/mm²"!
While meeting the "AL6" standard for the mechanical properties of non-metallic screw components according to JIS B 1057, the adoption of high-strength aluminum alloy "DK50" for automotive use, along with advanced forming technology for cold forging and the implementation of special heat treatment to address stress corrosion cracking, has achieved "tensile strength of 600 N/mm² and yield strength of 500 N/mm²."

basic information
★7000 Series High-Strength Aluminum Alloy ARK600 Ultra-High Strength Hex Bolt White Anodized "Benefits of Using ARK600" 1. Weight Reduction - With a specific gravity of 2.8, it is about 1/3 the weight compared to iron or stainless steel, which has a specific gravity of 7.85. 2. High Specific Strength - The thermal expansion rate of aluminum is approximately twice that of steel, and for bolts of the same weight, aluminum has a specific strength four times that of steel. 3. Galvanic Corrosion Prevention - Avoids galvanic corrosion when fastening aluminum to aluminum. 4. High Conductivity - High electrical conductivity allows for good reflection of electromagnetic waves and heat. 5. Recyclability - Can be recycled without disassembly when used with aluminum components. Proposal Examples - Proposals for the increasing demand for weight reduction in EVs, railway vehicles, and solar energy-related applications. - Suggested as a measure to prevent galvanic corrosion in aluminum fastening for aluminum structures and frames. (Note: The adoption of aluminum is increasing in various fields for weight reduction and fuel efficiency, leading to the emergence of galvanic corrosion issues.)
