That's a great question! There are many materials that can be pounded without shattering, depending on what you're looking for. Here are some examples:

Metals:

* Steel: A very strong and durable metal that can withstand significant force.

* Aluminum: Lightweight and malleable, making it suitable for shaping and bending.

* Copper: Another malleable metal that can be worked into various shapes.

* Gold: A soft but very malleable metal that can be pounded into thin sheets.

Other Materials:

* Rubber: Flexible and resilient, able to absorb impact.

* Plastic: Some plastics are designed to be durable and resistant to impact.

* Wood: Certain types of hardwood, like oak or maple, can be quite strong and resistant to shattering.

* Leather: A tough and flexible material that can withstand pounding.

Important Factors:

* Material Thickness: Thicker materials are generally more resistant to shattering.

* Material Type: Different materials have different properties and strengths.

* Force Applied: The amount of force used will affect how the material reacts.

For a more specific answer, I need to know what you plan to pound and what the purpose is.

For example:

* Are you looking for a material to make a tool for pounding other things?

* Are you looking for a material to create a sculpture?

* Are you looking for something to protect from impact?
