Sacrificial aluminum anode

1 The Main performance

The driving voltage is low, the weight is light, and the current efficiency is high.

Executive standard: GB/T 4948-2002

Sacrificial aluminum anode-1

Sacrificial aluminum anode-1

Sacrificial aluminum anode-2

Sacrificial aluminum anode-2

2 The Product classification:

1) Ordinary aluminum alloy sacrificial anode

2) Highly activated aluminum alloy sacrificial anode

3) High efficiency aluminum alloy sacrificial anode

4) High temperature resistant aluminum alloy sacrificial anode

5) Bracelet aluminum alloy sacrificial anode

3 The scope of application

Sacrificial magnesium anode are suitable for cathodic protection of metal corrosion protection for ships, machinery and equipment, marine engineering and harbor facilities, pipelines, cables etc facilities in sea mud.

4 The product features

The aluminum anodes produced by our company can prevent corrosion of steel structures in seawater, and are widely used in the corrosion protection of ship hulls, pressurized water tanks, seawater pipelines, port and wharf facilities, marine engineering, drilling platforms, condensers, etc. Because the performance of aluminum anode is affected by the chemical composition of the alloy, we provide aluminum alloy combinations with different compositions to meet customer requirements. Our company currently implements the standard GB/T 4948-2002. Different sizes can be customized according to customer requirements!

5 The Use matters

1)Avoid collision with steel structure   

2) Not recommended for use in soil
