HARD ANODIZING
Hard Anodizing process one step
Anodizing a metal part involves putting it into a liquid that is electrically conductive, typically an acid solution, called an electrolyte. But the regular process involves many steps to arrive to produce an uniform coating.
Our one step process involves just anodizing bath. Production of an anodic layer, whose thickness depends on the applied current, is chosen according to the final application or customer’s request. Control board and the special rectifier made our job easier, less time to produce the layer and more environmental. Let’s take you for a tour!
ANOD-SWEETMAG
This new and exciting treatment available through AnodAM inc, the first North American established leader in Magnesium, cast magnesium, cast aluminum, titanium, tantalum, hafnium anodizing, offers a multitude of significant benefits:
- Unique one step anodizing for light metals and their castings.
- Approved MTQ (Minister of transport of Quebec)
- Non-chrome. RoHS.
- Heating insulation (close porcelaine)
- Non heat surface dilatation ; resist until 1800°C
- Treatment for any cast magnesium alloy.
- Treatment for any cast aluminum alloy even A 383.
- Possibility to achieve 14,000 hours salt spray results on painted A360 and 8000 hours salt spray on painted A383 (cast aluminum)
- Possibility to achieve more than 2000 hours salt spray results on painted magnesium AM60 and EE43
- Compatible with oil and lubes.
- This trade mark technology it is a special anodizing treatment suitable for metals like:
- Magnesium
- Aluminium
- Tantalum
- Hafnium
(Especially cast alloys difficult to treat in conventional sulphuric acid solutions)
even when joined together in a sole mechanical part.
Anod-SweetMag™ technology
Aluminum alloy surfaces will keep their apparent shine in a dry environment due to the formation of a clear, protective layer of oxide. In a wet environment, 
galvanic corrosion can occur when an aluminum alloy is placed in electrical contact with other metals with more negative corrosion potentials than them.
The most used way to protect the casting surface is painting. But we cannot paint the metal without treatment.
The cast aluminum and magnesium anodizing with Anod-SweetMag™ process was started in 2009 in QC, Canada by AnodAM team work. The process was adapted since 2010 to meet the cast aluminum A 383 corrosion protection expectations. In 2011 Metal Protection Lenoli take part of the technology research and install the pilot line. The first series of tests and corrosion protection salt spray tests overpass the expectations (14,000 h salt spray on cast A360)(customer results available if required). Magnesium AZ91D met 1800 h salt and Magnesium Elektron 43 meet 2000 h spray corrosion protection (customer results). In 2014 the process line was finalized.
Description:
What is Anod-SweetMag™ process?
It is a light alkaline anodizing.
A wide range of amazing options are opened if a proper non toxic alkaline solution is used with a suitable machine and correct procedure.
High silicon cast aluminum become white and aesthetic and suitable to be used standalone or as a base for high corrosion resistant powder coating.
Production of an anodic layer, whose thickness depends on the applied current, is chosen according to the final application or customer’s request.
