Aluminum pneumatic cylinder tube is precision extruded or drawn from JIS A6063TD-T5 alloy, with H9 ID tolerance, RZ3.2S max roughness, and a 30μ±5μ anodic oxide film at HV400 hardness. At about one-third the weight of steel tube, it resists oxidation naturally, without relying on an added chrome layer — ideal for low-to-medium-pressure pneumatic cylinders prioritizing light weight and fast cycling
Highlights
- About 1/3 the weight of steel tube — Substantially reduces overall pneumatic system mass and inertia, ideal for robotics, pick-and-place automation, and portable air tools
- Naturally oxidation-resistant — Aluminum resists corrosion without an added chrome layer; anodizing further improves durability in humid or cleanroom settings
- 30μ±5μ anodic oxide film at HV400 hardness — Provides added wear protection and extends cylinder service life
- ID roughness RZ3.2S Max (better than 0.4μm Ra) — Typically smoother than unhoned steel tube out of the box, giving smoother piston travel and lower seal wear
- H9 ID tolerance — Suited to standard fit requirements in low-to-medium-pressure pneumatic cylinders
- Easier to machine, cut, and drill — Lower tooling wear and shorter production cycles than steel, ideal for rapid prototyping and custom cylinder designs
- Best value for low-to-medium-pressure systems — Lower tensile strength than E355, SAE1026, SAE1020, STKM13C seamless tube, but balances cost, corrosion resistance, and light weight for pneumatic applications

Technical Features
- 輕量化降低系統慣性與能耗 — 鋁合金密度約為鋼材三分之一，大幅減少氣壓缸整體質量，特別有利於高頻率往復動作的自動化設備，降低慣性負載與能量消耗
- 天然耐蝕特性簡化防蝕設計 — 不同於鏜光無縫鋼管需額外鍍鉻才能防蝕，鋁合金本身即具備一定耐氧化能力，經陽極處理後更能適應潮濕、潔淨室等環境，簡化防蝕工序
- 陽極氧化膜提供額外耐磨保護 — 30μ±5μ厚度、HV400硬度的陽極氧化層，有效抵抗活塞往復磨損，延長使用壽命
- 精密表面免除額外鏜光工序 — 鋁合金氣壓缸管的內徑表面通常優於0.4μm Ra，多數情況下無需如鋼管般額外進行珩磨或滾壓加工即可達到密封相容表面
- 易加工特性加快打樣與客製化流程 — 鋁材切削、鑽孔加工難度低於鋼材，降低刀具耗損並縮短生產週期，適合需要快速打樣或多樣化尺寸客製的專案
- 中低壓應用的最佳性價比選擇 — 雖抗拉強度不及E355鋼管、不適用於高壓液壓場合，但在中低壓氣壓系統中，鋁管在輕量化、耐蝕性與成本間取得優異平衡
