Our Sheet Metal Material Options
Aluminum
Commercially, aluminum is the most sought-after material for sheet metal manufacturing. Its popularity is due to its adaptive qualities and its high thermal conductivity and low resistance rates. Compared to steel—another common sheet metal material—aluminum is more cost-effective and has a higher rate of production. The material also generates the least amount of waste and can easily be reused.
At Marigold Rapid, the below four subtypes of aluminum are most used for making sheet metal prototyping parts, other types may also available upon request:
Aluminum 6061-T651
Aluminum 5052-H32
Aluminum 5074
Aluminum 6082
Stainless Steel
Stainless steel is the low carbon steel that contains a minimum of 10% chromium by weight. The material properties associated with stainless steel have made it a popular metal within a broad range of industries, including construction, automotive, aerospace and more. Within these industries, Stainless steel is versatile and is an effective choice for many applications.
At Marigold Rapid, we mainly use below four subtypes of stainless steel materials for producing sheet metal parts, but other materials are also available upon request:
SUS 301
SUS 304
SUS 316
SUS 430
Steel
Steel offers a number of beneficial properties for industrial applications, including rigidity, longevity, heat resistance and corrosion resistance. Sheet metal prototypes made out of steel are ideal for producing complex designs and parts that require extreme precision. Steel is also cost-efficient to work with and has excellent polishing properties.
At Marigold Rapid, we mainly use two subtypes of steel materials for sheet metal parts:
Cold Rolled Steel
Galvanized Steel
Anodizing
Anodizing is widely used for sheet metal parts. Anodizing helps to resist corrosion, increase surface hardness, improve resistance to wear and dissipate heat.
At Marigold Rapid, we normally use Type II anodizing, which allows us to add tints or dyes to prototyping parts to enhance their looks. Type III is also available upon request, it is often applied for surfaces that need to be extra hard.
Sandblasting
Sandlasting is used to clean and deburr parts, it can be an independent process or a preparation for later surface finishes, such as anodizing or painting. It involves the controlled spraying of the abrasive media against the surface of the product. Sandblasting also imparts unique textures, frosting, pebbling,etc.
We can also offer aquablasting and bead blasting to create identical surface finish with very low costs and short lead time.
Powder Coating
Powder coating is a process of coating metal with a plastic finish applied in powder form and baked to a fluid state to bond it to the metal surface.
Powder coating is mainly used for coating of metal prototypes, such as household appliances, drum hardware prototypes, automobile prototypes, motorcycle prototypes, and bicycle parts.
At Marigold Rapid, the most popular colors to apply for powder coating are: black, silver, white, blue and red, but we can also provide other colors upon customer request.
Brushing
Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. Brushing finish is produced by mechanically polishing or wearing away the outer surface of the metal. Brushing finish can be applied overall or selectively, in one or multiple directions.
We offer brushing surface finish mainly for CNC machined rapid prototyping parts or sheet metal prototypes.
Painting
Painting is one of the most widely used surface treatment in rapid prototyping parts or even volume production. With painting we can achieve different kinds of finishes, such as matt painting, glossy painting, textured painting, soft touch painting, and in theory any color is possible upon customer request.
At Marigold Rapid, painting process is also applied for many different industries such as electronics, medical devices, outer enclosure prototypes, wearable device prototypes and automobile parts prototypes.
