5083 round bar is a cylindrical marine-grade aluminum bar made from the non-heat-treatable 5xxx alloy 5083 (AlMg4.5Mn0.7). Its high magnesium content delivers outstanding resistance to seawater and industrial-chemical corrosion, while its weldability and post-weld strength retention make it a dependable choice for critical structures.
Round bar is commonly used for shafts, pins, supports, and machined components in shipbuilding, LNG equipment, and offshore service where corrosion resistance cannot be compromised.
Linsy supplies 5083 round bar in the size ranges below; other diameters and lengths are available on request.
| 脾气 | 直径(毫米) | 长度(毫米) |
|---|---|---|
| O, H111, H116, H321 | 6 – 400 | 1000 – 6000 |
Bars are supplied sawn to length from stock; tighter tolerances, centerless grinding, and CNC machining can be arranged.
5083 round bar maps to the following designations:
Bar and profile supply typically follows ASTM B221 and EN 755; marine and pressure-equipment projects may reference additional classification-society or ASTM B928 requirements.

不可热处理强化类别中的强度.
在加工硬化铝合金中,5083在保持良好的延展性的同时,提供了最高的强度水平之一。应变硬化状态(H116、H321、H32)提高了屈服强度,而不会牺牲太多成型性。.
5083在极低温度下保持韧性,不会变脆,这就是为什么它被广泛用于液化天然气储罐和低温压力容器。.
H116和H321等状态被指定用于海洋服役,因为它们与通用状态相比,具有改进的抗剥落腐蚀和抗应力腐蚀开裂性能。.

船用铝合金板:5052与5083 — 如何做出最佳选择.
No. 5083 is non-heat-treatable and is supplied only in annealed (O) or strain-hardened (H) tempers.
H116 or H321 are the usual marine choices, offering good strength with improved resistance to stress corrosion cracking. O or H111 suit parts that need extensive machining or forming first.
Yes. We provide sawing, CNC turning, and finishing, and ship every order with an MTC.
5xxx fillers matched to the base alloy, typically 5183 or 5356, depending on the joint and service conditions.
典型定制交货期为 10 至 60 天,具体取决于状态、尺寸及订单数量。常备状态产品通常可更快发货。.
是的。每笔订单均附带材质证明书(MTC),其中报告化学成分、力学性能及适用标准。可根据要求提供 SGS 或第三方检验报告。.
