一：Comparison of durability: 3003 alloy can form alumina film with the atmosphere to prevent further corrosion. For use in civil buildings, there is a 15-20 year warranty on the coating. The design life of the building is more than 50 years. Generally, the product warranty period is 25 years. Color steel plate in humid air and rain, snow water erosion is easy to corrosion rust caused by fracture accidents, especially rivets, joints.
二： weight comparison: 3003 alloy weight is light (density of 2730kg/m3); Color steel plate weight is heavy (density is 7850kg/m3).
三： strength and steel comparison: 3003 alloy aluminum alloy has magnesium, manganese content, so it has a certain strength and stiffness. But the internal stress and hardening, strength of aluminum alloy plate has no obvious yield point, not as good as color steel; Color steel plate strength and stiffness is better. Not easy to deform, etc.
四： appearance comparison: 3003 alloy can be divided into non-paint (hammer, embossing, pre-passivated alumina surface treatment, etc.) and paint (PVDF, SMP, PE, etc.); Color steel plate can be divided into non-painted (hot aluminum zinc alloy steel strip: light plate) and painted (PVDF, SMP, PE, HDP, etc.).
五： lightning protection performance: 3003 alloy thickness is generally 0.7mm and 0.9mm, can be directly used as lightning protection lightning receiver (national specifications & LT; < Code for lightning protection design of buildings > GB50057), avoid perforation in the roof; Color steel plate generally adopts 0.5mm thick aluminum zinc plating and galvanized steel plate, can not be directly used as lightning arrester, need to set up lightning arrester (such as lightning rod).
六：safety and fire: 3003 alloy melting point is low (660 degrees Celsius). High temperature performance is poor, 150 degrees above that the rapid loss of strength. In the event of a fire, the roof is easily burned through, so that the fire spreads outwards, but not inwards, which helps firefighters to extend the fire hose from the top; The melting point of color steel plate is high (1515 degrees Celsius).
七：molding: 3003 alloy has good weldability, high plasticity, low temperature environment, the strength and ductility of aluminum alloy can be improved, has good low temperature performance; Color steel plate steel is prone to cold and brittle at low temperature.
八:cost-effective: 3003 alloy cost-effective: light weight, waterproof, easy to bend arc, good three-dimensional visual effect; Color steel plate cost performance is low: heavy quality, waterproof slightly poor, strong steel, bending arc slightly poor, artistic effect is not good.
In a word, if you need any material ,except 3003,our company have other materials to meet all your need, for like 5183 ,8077 1050,1060 etc.
