Description

Our MMO canister anodes are fabricated from high-tensile titanium that complies with the commercial ASTM B338 Grade I standard. The elemental composition limits for ASTM B338 Grade I and Grade II titanium are specified in the table below:

Element	Grade I (Max. Content)	Grade II (Max. Content)
Iron (Fe)	0.20%	0.30%
Carbon (C)	0.08%	0.08%
Nitrogen (N)	0.03%	0.03%
Hydrogen (H)	0.015%	0.015%
Oxygen (O)	0.18%	0.25%
Single Impurity (Each)	0.10%	0.10%
Other Impurities (Total)	0.40%	0.40%
Titanium (Ti)	Remainder	Remainder

Technical Parameter
Our MMO canister anodes feature a standard iridium-tantalum (Ir-Ta) mixed metal oxide coating, which is specifically recommended for applications in soil environments with zero or low chloride ion concentrations.Accelerated life tests conducted by an independent third-party laboratory have validated that our MMO coating delivers superior performance compared to alternative products available in the market.

Customization Available: We can tailor the coating formulation by adjusting noble metal oxide ratios and coating thickness to match specific operational requirements.

The key technical specifications of the standard coating are as follows:

Technical Parameter	Performance Specification
Coating Composition	IrO₂, Ta₂O₅
Coating Thickness	5–10 μm
Coating Uniformity	Min. 85%
Recommended Service Environment	Soil (low/zero chloride content)

Electrochemical Performance
The current output of MMO canister anodes varies across different service media, ranging from soil to seawater. Anode service life can be extended by either increasing the coating thickness or reducing the operating current density.
The table below outlines the electrochemical performance of YUXI MMO tubular anodes in a coke breeze environment at a current density of 100 A/m²:

Anode Dimensions (Metric / Imperial)	Current Density	Current Output	Lifetime
Φ50×1200 mm (2” × 47.2”)	100 A/m²	19.0 A	25 yrs.
Φ32×1220 mm (1-1/4” × 48”)	100 A/m²	12.0 A	25 yrs.
Φ25×500 mm (1” × 19.7”)	100 A/m²	4.0 A	25 yrs.
Φ25×1524 mm (1” × 60”)	100 A/m²	12.0 A	25 yrs.
Φ25×1000 mm (1” × 39.4”)	100 A/m²	8.0 A	25 yrs.
Φ19×1000 mm (3/4” × 39.4”)	100 A/m²	6.0 A	25 yrs.
Φ16×1000 mm (5/8” × 39.4”)	100 A/m²	5.0 A	25 yrs.
