The Aluminium Properties
Between all metals, aluminum excels for its high thermal conductivity, which in addition to allowing a large amount of energy savings to reach the cooking temperature of the food, spreads heat evenly from the bottom to the walls while avoiding overheating during cooking concentrated with consequent carbonization of the surfaces of the same. Homogenous cooking of meats and foods in general is at the basis of the preservation of their nutritional and organoleptic properties.
LOW WEIGHT AND MANAGEABLE
The aluminum weighs about 1/3 of the water and about 1/4 of the copper and therefore the same size of the pots are extremely light and easy to handle both during cooking and during cleaning.
HIGH MECHANICAL SOLIDITY
In this regard, it is enough to think that aluminum alloys are the basis of aeronautical constructions, so this metal, although lightweight, is extremely reliable.
GHA® is the latest and most innovative technology applicable to the surfaces of all aluminum alloys (light alloys), consists of a special anodic oxidation treatment with a programmable thickness of 1 to 100 μm, followed by sealing of microporosity by ion of Silver (Ag +).
The high hardness of anodic oxide, HV 500-550, combined with the extraordinary properties of silver ions, give the surface treated biotechnological properties of extreme interest (see Table 2), ranging from the pharmaceutical and Food to the technical and scientific one:
– Industrial machine components
– Automotive components
– Office machine components
– Cooking elements
– House elements
– Electronic components
– Thermal radiators
– Clothing, electric blankets
– Air conditioning filters
Notice that the thickness of the treatment, ranging from 1 to 100 μm, is unremovable because the anode oxides form directly on the surface of the piece, which is the anode, generating an oxidized layer that for about 50% diffuses inside and for the other 50% increases on the surface.
Properties of Silver Ag + ions
- High antibacterial and antimildew (bacteriostatic)
- Low coefficient of friction, self lubrication and resistance
- Corrosion resistance
- High thermal conductivity and high thermodynamic performance
- Electrical and anti-static conductivity
- Ability of absorbing heat and re-storing it with ultra-infrared waves
|Aluminium||70÷100||680°C||0,44||100 hour||102 hour|
|G.H.A.®||500÷550||2100°C||0,025||10.000 hour||105 hour|
|Hard Oxide||500÷550||2100°C||0,15||200÷500 hour||103 hour|
GHA® treatment is also extremely cheap, beacause it uses silver, noble and expensive material, atomic phase, small and homogeneously distributed, particularly effective because the Ag + ion is always ready to interact by giving the listed properties.
