tinplate for metal can and beer caps Brazil
TINPLATE(SPTE）:
Tinplate is a kind of cold-rolled,low carbon shin steel coils or sheets coated both side by pure tin for packing use ,Also called as Electrolytic Tinplate,Tin Plate Sheets,SPTE.
As Tin is corrossion and anti-rusty, so tinplate combines the strength and formablity of steel and the corrossion resistance of tin to produce a new materials that is anti-rusty,
non-toxic,highly strongly and ductile.
Features of Electrolytic tinplate:
Tinplate is with tin-coating, so with strong resistance to rust,that is why safely for food and beverage packing,also has an beautiful metallic luster
for the final bright and silver surface .
Hence Tin plate have the follows features:
Excellent Corrosion Resistance
Safe for food and beverage packing
Excellent Properties For Can -Making
Wide Choice
Low weight, high strength, eco-friendly and economical
How is tinplate produced at factory ?
Hot Rolling-Pickling-Cold Reduction- Electrolytic Cleaning-Continous Annealing (CA) or Box Annealing(BA)-Temper Rolling-Double Reduction-Tinning-Plating-Flow-melting-Passivation-Packing
Applications
Over 90 percent of the material that thyssenkrupp produces in Andernach is used in the packaging industry.
Major application areas for this material are
cans for food and pet food
packaging for chemical or technical products
aerosol cans
closures
beverage cans
Standard:
We can offer confirm to JISG3303 / EN10202 / ASTM A 623 AISI623
Coating Mass /Coating weights for tin
there are two types coating of mass: the Equally coated Mass(in which both sides have the same mass of tin coating) and the Differentially Coated Mass(in
which one side is moreheavily coated than the other )
