SolidWorks toolbox components do not have a material applied to them. A material can be applied to toolbox components so that they insert with that material. To do this, please follow the steps below:
Open up the Toolbox Settings by going to Start->All Programs->SolidWorks->SolidWorks Tools->Toolbox Settings or by clicking on the Configure Toolbox button in the design library.
Click on Step 2 to "Customize your hardware"
Create a custom property by clicking on the button shown below.
In the Custom Property Definition, be sure to input the Property Name such as Material. Changing the type from Textbox to List will make the option "Link to SW material" appear. Enabling that option allows for a material to be selected on the right. This value entered here will appear in the Text/Expression of the custom property for the toolbox component. Multiple materials can be listed on the right.
Click OK to close out of the dialogue box and browse to the folder level or toolbox part that to apply a material to. Then click the checkbox to enable the custom material and click on the radio button to select the material to be applied.
After applying the material, save the toolbox settings.
The components should then be inserted with the material applied, as well as having a custom property for the material.
