ASTM B209 AA5251 5251 Alloy Aluminum Coil Chinese Supplier

Product Specification

ASTM B209  AA5251 Aluminum Coil 5251 Alloy Aluminum Coil Chinese Supplier

Alloy 5251 is a non-heat treatable rolled product supplied as either sheet or coil. 5251

is stronger than 5005 and is used in applications requiring more structural integrity or

impact resistance. 5251 has excellent corrosion resistance, medium static strength, me

-dium to high fatigue strength, good weldability and very good corrosion resistance esp

-ecially in marine applications.

Our Company 

♦ We had streamlined and standardized our workflows so everyone can work together more smoothly,

   avoid any mistake, and get more done.

♦ A comfortable and well-lit work environment, combined with a reasonably arranged office layout,

  fosters a positive work attitude, healthy interpersonal relationships, and sustained team growth

  motivation, while enhancing team cohesion and a sense of belonging.

♦ Left 1--this is what I look like — nice to meet you here.

Our Factory

1) We introduced world-leading technology and equipment, including advanced vertical intelligent

    storage, logistics systems, and finishing lines, to meet all production demands for aluminum plates,

    coils and strips.

1) We have built portfolio advantages with multiple products, and we are good at big size and mass

    production.

2)In the future, we will focus on creating value for customers, caring for employees, and serving

    society, striving to become a global leader in high end flat-rolled products.

We use the World-advanced Equipments

These are some samples we made below : 

Ocean Shipping

For oversize sheet, we use Flat Rack Container

1) We use suitable securing material, such as wooden blocks, steel straps, and ratchet tie-downs

     to firmly fix the aluminum plates to the flat rack.

2) To prevent possible exposure to seawater or rain, we cover the entire cargo with waterproof tarps.

3) We make sure these sheets are loaded with a low and evenly distributed center of gravity to avoid

     tilting during the transportation.
