SEALIUM®

Sheets and plates

Description

This specification defines the properties and characteristics of Sealium® marine grade aluminium alloy, delivered by Alcan Marine as sheets or plates.

Created and registered by Alcan Marine, Sealium® optimizes the overall productivity of shipbuilders and the performance of vessels in general as it makes them more robust, safer, and user-friendly.

In just a few years, Sealium® has become the international industry reference for fast ferries. SEALIUM®

片材和板材

描述

此详述对由加铝船用铝部门研制开发的Sealium® 船用级铝片材及铝板材的性质和特性进行了定义。

由加铝船用铝研制开发并注册的Sealium®铝材通过使舰船更加的强韧，安全以及简单易用从而将造船企业的整体产能与舰船的整体表现有机整合。

在仅仅数年的时间里，Sealium®已经成为了国际快船制造业的业内标杆。

Applications

Sealium® may be used wherever a stronger welded aluminium structure is desired, from hulls to superstructures. Marine structures benefit from the excellent corrosion resistance offered by Sealium®.

Smaller boats(<50 m) benefit from improved scantlings, which translate into structural weight savings on patrol craft, increased strength on workboats or added interior space in luxury yachts. Larger vessels(>50 m) profit from the increased strength and improved fatigue behavior of Sealium®. Cruise ship superstructures can be lightened further while improving stability and not compromising strength or corrosion resistance.

用途

Sealium®可以应用于所有需要更高强度的焊接铝制结构的甲板以及甲板上层结构。船体结构极佳的抗腐蚀性亦得益于Sealium®.

Sealium® 的提高了的结构造型使小型船只（< 50 m）获益，如巡逻艇获得了更高的减重，工作船提高了船身强度，豪华游艇也获得更大的内部空间。大型舰船从Sealium® 获得了增强的船身强度并延长了的疲劳寿命。超级游轮在不降低船身强度以及抗腐蚀性的前提下提高稳定性后，可以获得更大的减重。

Advantages

15% higher welded yield strength than standard 5083 alloy:

·Increased margin of safety from same scantlings.

·Significant weight savings from optimized scantlings.

Proven improved corrosion resistance.

Increased fatigue strength.

Same usage properties as 5083 alloy:

·Formability: Same cutting, bending and shaping.

·Welding: no change in welding procedure, consumables or heat induced deformation. Greater recycling value for the entire Sealium® welded assembly.

优点

比标准5083合金的焊接强度高15%：

·比相同的结构造型有更高的安全系数

·整合结构具有显著的减重性。

具有已证实的抗腐蚀性。

延长了疲劳寿命。

整个Sealium船用型材的焊接总成都有更高的回收价值。

具有与标准5083合金相同的使用属性：

·成型性：相同的切割，弯曲和成型。

·焊接：在焊接步骤，可熔性以及受热变形上没有任何改变。

Corrosion resistance

Sheets or plates made of Sealium® marine grade aluminium alloy offer a guaranty of intergranular and exfoliation corrosion resistance for severe marine applications as described in ASTM B928 (marine hull construction or marine applications where frequent or constant direct contact with sea water is expected). Accelerated tests and marine exposure (air and immersion)

as well as experience have proven the long term corrosion resistance of Sealium®. Sealium®

offers a better mechanical resistance on welded components than standard alloy 5083 with a good or better corrosion resistance.

抗腐蚀性

由Sealium®船用级铝材合金制成的板材与片材可实现在ASTM B928条款中提到的抗晶体及剥落物腐蚀的抗

性（频繁或持续地与海水接触是可以在船体构造或航海应用中所预见的）。持续累加的测试和海洋环境腐

蚀测试（空气及海水浸泡）已经验证了Sealium®的长效抗腐蚀性。Sealium®对焊接部件提供了相较于标准5083合金更优的力学抗阻以及抗腐蚀性。
