Recently we had a case using SUS 410 screw when penetrate into steel purlin, the tip and threads broke. So we carried out hardness test to prove. Hardness is a characteristic of a material, not a fundamental physical property. It is defined as the resistance to...

SUS 410 self-tapping screw Material:                             410 stainless steel: 1Cr13 Not 100% rusty free Martensitic stainless steel C1 30H Hardness 300HVmin SUS 410 self-tapping screw Description: Drilling, thread-forming and fastening in one step Connect components in one step Reduces assembly times Save tool changes and drilling tool costs Instructions: As stainless steel...

SUS 410 self-tapping screw Type 410 is hardenable, straight-chromium stainless steels which combine superior wear resistance of high carbon alloys with the excellent corrosion resistance of chromium stainless steels. Oil quenching these alloys from temperatures between 1800°F to 1950°F (982-1066°C) produces the highest strength and/or wear...

In previous post Aluminum alloys https://www.solaracks.com/aluminum-alloys/ we have mentioned most common aluminum in solar mounting material is 6005. 6005-T5 aluminum is 6005 aluminum in the T5 temper. To achieve this temper, the metal is artificially aged until it meets standard mechanical property requirements. It has...

Bauxite mining, the aluminium production starts with the mining of bauxites, an aluminum rich mineral in the form of aluminium hydroxide. About 99% of global bauxite supply is found in tropical areas. The name “Bauxite” comes from “Baux-de-Provence”, the French village where the mineral was first...

In solar mounting system industry, when you see aluminium alloy is 6005, 6061, 6063. There is T5, T6 after the 4 digits number, they are tempers. Aluminum tempers are named using a letter, followed by one or more numeric digits. The designations F (as fabricated) and...

In solar mounting system industry, mostly used aluminum alloy is 6005, 6061, 6063. What is the difference? Metals where the dominant alloying element is aluminum (Al, also spelled aluminium). Aluminum alloys are subdivided by fabrication method (wrought or cast, typically). Wrought alloys are further subdivided by...

In the solar mounting system, we need the structure to be solid to support the whole solar PV system, and last decades in severe weather conditions, outdoor environment where there is rain, sometimes salty, chemical. Aluminium offers a rare combination of valuable properties. It is one...

Solaracks design and manufacture aluminum solar mounting system, we deal with the material aluminum every day. What is Aluminum? Why we choose this material for the solar mounting structure with design lifetime 25years? We will present a series of articles for more understanding of aluminum. Aluminium...
