Armour Preinsulated Aluminium Refrigerant Tube
Armour Pre Insulated Tube ensures that every tube to be installed is free of leaks and clean. All All tubes are pre-pumped with nitrogen gas and when cut, an oozing sound of gas siqnals that the tubes are 100% leak free.
Armour Preinsulated Tube able to withstand burst pressure of more than 1000psi without sign of leakage, comply to R410.
Today aluminium widely considered as the best alternative metal to copper in HVAC & R industry. Since brazed aluminium heat exchangers were successfully introduced in automotive air-conditioning systems, the interest of using aluminium in stationery refrigeration and air-conditioning has grown.

Aluminium has many excellent characteristics that make it highly suitable for use in HVAC & R industry.  Aluminum has excellent formability and strong.  Aluminium has a unique properties,  Unlike most steel grades, aluminium does not become brittle at low temperatures. Instead, its strength increases. At high temperatures, aluminium’s strength decreases.

Aluminium is an excellent conductor of heat and corrosion resistance. This metal does not react with dry air, but in moist air, they will form an oxide layer on its surface. A very thin layer that forms around 10-8m but was able to prevent the aluminum from further oxidation reaction and prevent it from reacting with dilute acid. The layer is self-repairing if damaged and also impermeable to water.
Aluminium reacts with the oxygen in the air to form an extremely thin layer of oxide. Though it is only some hundredths of a (my)m thick (1 (my)m is one thousandth of a millimetre), this layer is dense and provides excellent corrosion protection. The layer is self-repairing if damaged.
One of the best known properties of aluminium is that it is light, with a density one third that of steel, 2,700 kg/m3. The low density of aluminium accounts for it being lightweight but this does not affect its strength. 
As the most abundant metal in the earth, the price of aluminum is lower and relatively stable than copper
