## Content

**Intro:** Mass, powder cost and shrinkage calculations all start with a density, and the right number depends on the alloy and the route. This reference lists common additive, MIM and powder metallurgy metals with their density, typical routes and short notes.

**Sections:**

#### How to use it

**Body:** Search by alloy name, UNS number, family or route. The density column gives the fully dense wrought value for wrought-equivalent alloys, and a typical sintered range where noted for PM and MIM designations. Copy the density into the build cost, nesting and shrinkage calculators to convert part volume to mass. The routes column shows which processes commonly handle the alloy, which narrows the make-or-print options.

**Bullets:**

- Use sintered density for MIM and PM parts, not the wrought value.
- Confirm alloy availability with your powder or service supplier.
- Check the governing specification for design values.

#### Understanding the routes

**Body:** Laser and electron beam powder bed fusion (PBF-LB, PBF-EB) produce near fully dense metal parts layer by layer. Binder jet prints a green part that is sintered, like MIM, and shrinks. DED deposits metal from powder or wire for repair and large features. Metal injection molding (MIM) molds feedstock, debinds and sinters, and suits small complex parts at high volumes. Press-and-sinter PM compacts powder in a die and suits axially pressed shapes at very high volumes.

#### Density, porosity and cost

**Body:** Density drives cost in two places. Powder price per kilogram multiplied by part mass sets material cost, and heavier alloys such as nickel and tungsten alloys cost more for the same volume. Porosity changes properties: PM structural parts at 6.6 to 7.0 g/cm3 have lower strength and ductility than wrought steel, and MIM parts at 95 to 99 percent density approach wrought properties. Fully dense AM parts may still need HIP to close internal voids in fatigue-critical applications.

#### Common mistakes

**Body:** Using wrought density for a porous PM part overestimates its mass, often by ten percent or more. Mixing trade names with standard designations is another problem: check composition and condition, not only the label. Alloys on this list that are marked difficult, such as 6061 aluminum in laser powder bed, usually need modified chemistries. Finally, powder and feedstock prices vary widely by size distribution and supplier, so use quotes, not list averages, for budgets.

**Cta:** If your item master and BOMs should carry density, route and material specifications consistently, we can help clean and structure that data in your ERP.

**Faq:**

#### Which density should I use for mass calculations?

**Answer:** For fully dense AM parts, use the wrought density. For MIM and PM parts, use the measured or specified sintered density, because porosity reduces mass compared with the wrought value.

#### What is MPIF Standard 35?

**Answer:** It is the Metal Powder Industries Federation standard that defines materials and designations for PM structural parts, with companion editions for MIM and other PM materials. It lists compositions, properties and design values used in drawings.

#### Why are some alloys marked difficult in some processes?

**Answer:** Alloy chemistry, thermal conductivity, reflectivity and solidification range affect printability. For example, standard 6061 tends to crack in laser powder bed fusion, and pure copper reflects infrared lasers strongly.

#### Is the density the same for powder and part?

**Answer:** No. Powder has apparent and tap densities that are well below the solid density because of gaps between particles. The values here are for solid material, which you use for part mass.
