Learn MoreAluminum 6000 series alloys (primarily Al-Mg-Si formulations) represent the sweet spot between structural mechanical strength, excellent machinability, corrosion resistance, and post-machining finish qualities. Silicon and magnesium are added in precise proportions to form Magnesium Silicide (Mg2Si), making this series highly heat-treatable and responsive to precipitation hardening protocols (such as T4, T5, and T6 tempers).
As a leading developer and manufacturer, Qingdao Kangjian Aluminum Industry Technology Co., Ltd. provides specialized 6061, 6063, and 6082 extrusions designed to perform under extreme shear stresses, dynamic aerodynamic drag, and highly corrosive marine atmospheres. We utilize advanced gas-cushion billet casting and computerized extrusion presses to keep structural impurities to a minimum, ensuring consistent structural integrity across every extrusion batch.

"To provide true Information Gain to global procurement heads, our engineers test grain size refinement. Our automated solution guarantees average grain sizes below 80 micrometers, which significantly prevents micro-cracking during heavy CNC milling, deep cold-forming, and automated MIG/TIG welding operations."
Qingdao Kangjian Aluminum Industry Technology Co., Ltd. — Pioneering lightweight and smart aluminum solutions from Jimo, Qingdao.
Founded in 2022 and situated in Jimo District, Qingdao, our company is a major player in aluminum extrusion, precision machining, and specialized metal surface treatment. Spanning over 200 mu with 80,000 square meters of state-of-the-art production floors and 4,000 square meters of administrative offices, we handle high-complexity procurement demands.
Operating an annual extrusion capacity of over 15,000 tons, our machinery inventory includes 5 high-precision extrusion presses ranging from 700T up to a robust 2500T press. We utilize computerized heating and cooling control systems on our extrusion presses to achieve tight structural properties and dimensional control over wide profiles.
We are the primary aluminum supplier in the Qingdao area for structural high-speed rail lines, urban subways, marine logistics systems, and automotive structural components. Our close proximity to the Port of Qingdao enables reliable shipping and direct sea routes to key markets like South Korea, Japan, Europe, and the United States.
Through consistent investment in advanced technology and machinery, we have expanded our client base across key industrial regions in China, including Anhui, Tianjin, Beijing, Guangdong, and Jiangsu, while sustaining a 30% average annual order volume growth rate.
We supply custom-extruded aluminum for solar mounting racks, custom automotive crash bars, LED profile channels, marine platforms, modular automation setups, and specialized medical apparatus framing.
We maintain comprehensive manufacturing certifications including ISO9001:2016, ISO14001:2016, IATF16949 for automotive standards, ISO22163 for rail, and specialized welding/bonding certifications such as EN15085, ISO3834, AWS, and DIN6701.
As industries transition toward cleaner processes and lightweight designs, the global demand for custom aluminum extrusions is growing rapidly. Across automotive, clean energy, and transportation sectors, purchasing managers are shifting away from heavy steel fabrications toward high-yield, heat-treatable aluminum profiles to reduce assembly weight and energy footprint.
For example, in electric vehicles (EVs), every 10% reduction in vehicle weight translates to approximately a 6-8% increase in battery driving range. As a result, automotive engineers rely on thin-walled structural members made from 6000-series alloys like 6061-T6 and 6082-T6. These alloys can absorb collision impact energy without fracturing, while allowing complex geometries to be extruded in a single piece to replace multiple welded steel parts.
Similarly, in renewable energy, solar PV arrays require structural brackets that can withstand coastal humidity and high wind loads for 25+ years. Utilizing 6005A-T6 or 6063-T6 aluminum with custom anodized coatings prevents galvanic corrosion and maintains mounting system integrity without requiring expensive ongoing maintenance.
Providing custom solutions from initial die design and alloy selection to final high-precision CNC machining.
We work directly with client design teams to model extrusion dies using 3D simulation tools. This reduces manufacturing trials and speeds up deliveries, even for complex profiles with varying wall thicknesses.
Our machine shop offers multi-axis milling, drilling, tapping, and counterboring. This allows us to deliver fully-finished, ready-to-assemble structural parts with tolerances as tight as ±0.02 mm.
We provide a variety of surface finishes, including matte and bright acid anodizing (up to 25 microns), weather-resistant architectural powder coatings, wood-grain heat sublimation, and chemical etching.
Heavy duty brackets, t-slot frameworks, automated conveyor guides, and pneumatic cylinders.
Crash management structures, chassis parts, battery housing frames, and interior trim tracks.
Durable, corrosion-resistant framing designed for long-term outdoor use and easy assembly.
Architectural curtain walls, framing systems, thresholds, and durable window casings.
High-precision, lightweight frames for hospital equipment, adjustable beds, and imaging machinery.
Cargo container walls, heavy-duty floorboards for commercial trailers, and high-speed rail elements.
Navigating global supply chain regulations and raw material tariffs requires a reliable manufacturing partner. We help our global clients address key supply chain risks through comprehensive compliance documentation, physical property certifications, and direct shipping logistics from Qingdao Port.
Every extrusion batch undergoes testing for chemical composition, mechanical properties, and coating performance. We supply verified Material Test Reports (MTRs) and mill test certs, showing compliance with ASTM, EN, and JIS requirements. We also offer customs clearance assistance and flexible delivery terms (FOB, CIF, DDP) to reduce logistics overhead.
Our technical team provides localized engineering support in both English and Chinese. We assist in auditing design files to make profiles easier to extrude, helping to prevent structural issues and reduce unnecessary production costs.
We continue to invest in manufacturing R&D to improve profile precision and material performance. Our current focus areas include:
Technical answers to common questions about alloy properties, structural capabilities, and custom extrusion orders.
