This year a foreign friend, bought a set of stage trusses from elsewhere, is 30% cheaper than ours,At the same time require us to cut prices,We attach great importance,We examine the market, from the raw materials to our own process costs have done the latest carding,Our prices still can't come down.We asked the old friend to send over his latest stage truss,We repeated research and found no difference in appearance,After striving for the consent of our old friends, we cut this stage truss and did various tests. We finally found out where the problems were and nalyzed it for everyone to hope to help.

High-quality aluminum:

1, visual inspection: the appearance and color to be consistent, beautiful and beautiful, uniform mechanical pattern without black graphite line, a high brightness and metallic luster.

2, feel: body smooth and glitch-free.

3, chemical properties: high-quality aluminum plant configuration melting furnace and online degassing and tube filtration and other high-end alloy manufacturing equipment to ensure that the alloy material requirements and meet the ROHS requirements, with corrosion resistance, corrosion resistance.

4, mechanical properties: high quality aluminum plant configuration multiple tensile testing machine to ensure that each aluminum tube in line with European standards and has fatigue resistance, high quality aluminum plant general mechanical properties beyond the European standards 15% - 25%, hardness : 15HW above. (Toughness and hardness are very good)

5, Technology: Plane gap, curvature, twist degree by high-precision implementation.

6, Traceability: The implementation of the most stringent of Europe's EN 102043.1 traceability standards.

Poor quality aluminum:

1, visual inspection: appearance and color dull, no brightness, no metallic luster, black graphite lines and mechanical pattern distribution is unequal, almost no appearance requirements.

2, feel: rough tube burrs

3, chemical properties: poor quality aluminum alloy melting plant capacity, the alloy is purchased, can not guarantee that the alloy is a real 6082 T6 material. (Because all the aluminum ingots purchased after melting back need to add a certain proportion of silicon and magnesium alloys)

4, mechanical properties: poor quality aluminum plant is not equipped with tensile testing machine, aluminum tube hardness test to determine the mechanical properties alone. (High hardness, low toughness, prone to brittle fracture)

5, technology: generally do not grasp how to squeeze high-quality 6082-T6 profiles of the process.

6, traceability: there is no traceability conditions.

In general, low-cost low-cost production of aluminum and high cost of high-quality high-quality aluminum production costs and low yield compared to high-quality aluminum than inferior aluminum processing fees per ton high 35% -45%.
