What type of blasting is used to clean aluminum alloys and stainless steel?

The use of aluminum oxide or garnet blasting is appropriate for cleaning aluminum alloys and stainless steel because these materials require a gentle yet effective cleaning method to avoid damage. Aluminum and stainless steel are both sensitive to overly aggressive blasting media that could lead to pitting or surface erosion.

Aluminum oxide is a hard, durable media that can effectively remove contaminants like surface oxidation, paint, and other debris without harming the substrate. Garnet blasting provides a similar benefit, offering a sharp yet non-aggressive approach that helps maintain the integrity of the metal surface while achieving a clean finish.

In contrast, other blasting methods are either too abrasive or less effective for cleaning these particular metals. Water jetting, while useful for removing loose debris, may not adequately prepare surfaces for coating applications. Sand blasting can be overly harsh on softer metals like aluminum and is typically better suited for tougher substrates. Vapor blasting, while a gentler method, might not provide the same level of cleaning effectiveness as aluminum oxide or garnet in this specific context.
